Look no farther if you're wondering whether Magnet Fishing is permitted in
  your region. Bridges are ideal locations for Magnet Fishing. These bridges are
  frequently readily accessible, and many are also utilized as dumping places by
  thieves. Weapons and safes may even be found beneath them in high-crime
  regions! Finding these hidden riches with a magnet may be a highly satisfying
  experience, and it's legal in most places.
    
Magnets made of neodymium
  Magnet fishing is a recreational sport that includes finding ferromagnetic
  items in bodies of water. It mixes treasure seeking with environmental
  awareness. Magneteers and neodemons are other names for magnet fisherman.
  These magnets may be purchased for less than PS10 and are widely accessible
  online. Magnet fishing is becoming more popular across the globe, particularly
  in continental Europe. The following suggestions are intended to assist you in
  locating magnetic items in waterways.
  Neodymium magnets are the most powerful forms of magnets. They are excellent
  for removing metal things from water. They are available in a range of
  strengths and styles to suit the function. Magnets are tested under ideal
  circumstances, which involve complete contact with a metal surface, to assess
  their pulling power. Metal products may be uneven or rusted, therefore these
  criteria may not always present. As a result, fishing with magnets in water
  may cause corrosion and breakage.
  Choosing a body of water is the first stage in magnet fishing. A body of water
  with a boat ramp and numerous additional places along the route may provide a
  wide range of things. Bends downstream of fast-flowing water, as well as
  regions near natural snags, are also useful sites to look for objects.
  Neodymium magnets may assist you in locating even more valuable artifacts in
  these areas. So, if you come across gold or silver on your journey, don't
  forget to stop by the neighboring museum!
  The use of magnets in fishing canals is not illegal in Scotland, although it
  is outlawed by the Canal and River Trust, which maintains over 2,000 miles of
  waterways. Many magnet fishermen, however, continue to break the restrictions
  and clean up after themselves. Magnet fisherman should be environmentally
  conscious and tidy up after themselves. If you do this, you may get a PS25
  fine.
  Neodymium magnets are the most often used magnets in fishing canals. These
  magnets are composed of iron, boron, and neodymium. If you want to attempt
  magnet fishing, be sure you use a neodymium magnet for the greatest results.
  There are various sorts of magnets, each with its own set of advantages.
The Palomar Knot
  Those wishing for a one-of-a-kind outdoor sport can go to the Palomar Knot
  magnet fishing canals. Many different sorts of magnets live in these
  waterways. Fish are attracted to magnetic lures by these magnets. Magnets work
  well in shallow, muddy locations, voids, and other areas with few people. Here
  are some pointers to help you have the greatest magnet fishing experience in
  San Diego:
  A common magnet fishing knot is the Palomar Knot. It is more durable and
  dependable than many other magnet fishing knots. It can support a load up to
  double its length. It is even possible to knot it in the dark. The Palomar
  Knot has various versions. The Double Palomar Knot involves two passes through
  the loop. It may be just as effective as a single Palomar knot when done
  appropriately.
  Magnetic fishing equipment is reasonably priced. All you need is a sturdy,
  long rope and a powerful retrieving magnet. The majority of magnetic artifacts
  found on seafloors are corroded and filthy. Make use of a strong, braided rope
  with a high breaking strength. A 5mm rope should enough for smaller magnets,
  while a 10-mm rope is required for bigger magnets. Finally, protect your hands
  from the moist surroundings by wearing rubber gloves.
  When selecting a magnet for magnet fishing, choose an area with considerable
  foot traffic. Avoid places with metal buildings or where fishermen are
  casting. Water activity and boat traffic are often ideal magnet fishing spots.
  For historic sites, an 800-pound magnet should enough. Furthermore, magnetic
  fishing in canals is permitted in much of Western Europe, however many regions
  need a permission. Furthermore, owing to World War II armaments, magnet
  fishing is forbidden in England.
  There are no unique regulations against magnet fishing in the UK, but if you
  want to use public waterways, you must acquire permission from the Canal and
  River Trust and the landowner. It's a fascinating way to discover hidden gems
  around the local rivers. Magnet fishing, unlike other types of angling, does
  not need a license or any other legal documentation. If you're uncertain, get
  in touch with the Canal and River Trust or your local city or council. If you
  come across any suspicious things, call the police right away.
Typical magnet fishing equipment
  A strong neodymium magnet plus a long line or hook are typical magnet fishing
  gear for canals. Fishing tactics differ based on the kind of area. A Magnet
  Fishing Spike may be required when fishing from a bridge, dropping the magnet,
  or casting from a boat. These things are often available at sports goods
  shops, but you may want to consider acquiring a couple.
  While magnet fishing, it is essential to wear gloves and a life jacket.
  Children will love this activity, but it is critical that safety rules be
  followed. To prevent electrocution, always wear life jackets, gloves, and a
  helmet. Be wary of explosives when metal detecting. Report anything suspect to
  authorities, and never touch explosives or firearms. Always notify someone of
  your whereabouts. This is not a pastime for the faint of heart.
  If you're fortunate, you could come upon a treasure box holding gold cash or
  an ancient WWI-era weapons. These are only a few of the more typical
  discoveries discovered by magnet fishers, but the list is endless! There's
  even a cash box with gold coins! In the canal, you may even find a WWII pistol
  or revolver. It is critical that you report these discoveries to the
  authorities and inform them of your journey.
  Another key aspect of canal magnet fishing equipment is safety. When fishing,
  always wear protective gloves. Because the magnet is slippery, it is best to
  draw it in using gloves. If you're fishing in an area where there are water
  plants or algae, you should take extra steps to prevent slipping into the
  canal. Keep yourself and any discoveries away from pathways. You'll be well on
  your way to catching fish after you've mastered these methods!
  Magnetic fishing line is also an essential piece of equipment. Make careful to
  tie your fishing line in a knot while preparing it. Despite the fact that
  there are hundreds of knots available, the figure 8 follow-through and the
  palomar knot are the most typically used for magnet fishing. They are both
  strong and simple to bind. Because you may use the same knot for both knots,
  make sure you master this one first.
Magnet fishing is legal.
  Magnet fishing canals is lawful in the United Kingdom, as long as you are not
  fishing on public land. Before you may fish in canals and rivers, you must
  first seek authorization from the Canal & River Trust, a government
  institution. Obtaining permission is not straightforward, however it may be
  challenging for people who do not own their own land. If you can't locate
  private property, you may magnet fish canals and rivers on other people's
  land.
  Canals are excellent locations to Magnet Fish, and many individuals have
  reported discovering an abundance of intriguing stuff throughout their
  expeditions. From gold coins to WWI weaponry, the choices are nearly
  limitless. You could even uncover something valuable on the collector's market
  if you're fortunate. The legality of magnet fishing canals is determined by
  where you reside. Magnet fishing is not permitted in certain regions, although
  it is permitted in others.
  Magnet fishing provides benefits in addition to the apparent hazards of canal
  fishing. Canals often feature lock and dam systems that regulate water level
  and flow. Magnet fishing may be prohibited in some regions because to the
  possibility of discovering artifacts buried under the sea. Magnets may also
  get trapped in pipes, drains, and grates. If you do uncover anything
  worthwhile, you may split the cost with the owner.
  Before planning a fishing expedition, it is critical to study the legality of
  magnet fishing. Some states have regulations against magnet fishing, which may
  surprise you. Even if you are permitted to use magnets in the state, you
  should always get permission from canal officials before embarking on a
  fishing expedition. If you want to use a magnet for gold prospecting, make
  sure you have the proper surface so that the gold debris does not end up in
  the water.
  The Canal & River Trust owns the majority of the canals in the United
  Kingdom. Magnet fishing is not permitted in public places or canals.
  Furthermore, the General Canal Byelaws from 1965 include no reference of
  magnet fishing. Instead, they discuss dredging the canals, which magnet
  fishing entails. Because the Canal & River Trust has little control over
  magnet fishing, it is widely seen as a nuisance.
