Fishing Magnets
Fishing magnets are not used to attract fish as their name suggests, but are a specially designed tool whose main function is to use strong magnetic forces to attract and retrieve ferromagnetic objects underwater.
This tool usually consists of a neodymium magnet and a durable rope.Users can put the magnet into the water, and once the magnet approaches a ferromagnetic object, it will be tightly attracted by magnetic force. Then users can pull the rope to retrieve the magnet and the attached object together.
