Similar to metal detecting, where objects are found on the ground using a metal detector, magnet fishing is about finding metal objects in water using powerful magnets. Have you ever imagined what could be at the bottom of the lake near where you live? There were interesting discoveries by people who were curious enough to tie a magnet to the end of a rope to throw it into the water, many of them being very surprised by what they found.
You need a very strong magnet for this type of fishing. The best thing is to find the strongest magnet and tie it securely to a rope. Remember that the pulling force of the magnet will be maximum when the metal object is completely flat. However, during magnet fishing, a flat contact would be difficult to achieve, because objects that are at the bottom of a lake for a long period of time tend to accumulate residues (soil, vegetation, rust, algae, etc.) and that is why it is advisable to get a much stronger magnet to compensate for these irregularities.
The best magnet to use for this type of fishing is a neodymium magnet, as their relatively compact size can have a huge pulling force. Neodymium magnets are rare earth magnets and are considered some of the strongest magnets available. As a note of caution, please be very careful when handling these magnets.
Magnet fishing is really an interesting and cheap outdoor hobby that anyone can do and it gives the enthusiast the chance to interact with the environment in a very unique way.
