Paul wrote with an idea on how to stop shark attaks on divers:
Why are magnets or battery operated magnets not inncorporated into wet suits for divers to deter sharks? Can an intense magnetic field not be generated underwater or would it adversely affect the diver?
What do you think?

You are welcome to try, and assured of an interested audience for your findings.

There is no known adverse effect on humans of a constant magnetic field up to 8 tesla.

There are several species known as "shark", with very different characteristics. AFAIK some respond to electric fields and some may use magnetic fields to navigate, but beware: your experiment in a tank with a 2 kg Common Dogfish may not map usefully to a 5 tonne Great White.
