Why are sharks afraid of magnets?

Okay I'll tell you but only if you promise to come back here,  select the desktop view and drop a serious share of the fortune you're gonna make once you know the answer.

First you have to know that most species of sharks must swim constantly to keep water flowing thru their gills to breath.

The second thing you need to know is that, although most people know about electric eels, fewer people realize that the oceans contain many species of electric fish, which is why sharks evolved sensors to detect magnetic fields.

Putting this knowledge together with the fact that electricity has a magnetic field, you realize that any magnetic field warns sharks that they are in danger of being stunned. Normally being stunned isn't so bad,  but for a shark it's terrifying because it means the danger of asphyxiation.  Because they can't swim if they're out cold and if they can't swim they can't breathe.

Okay, so how does this knowledge make you rich?  Well just sew magnetic threads into swimming suits and other water gear and presto, shark detects magnetic field and gets scared away.  Unless the customer likes being bitten by sharks you've just made a sale.

In fact beach municipalities would pay handsomely for shark repellant ropes they can anchor offshore to keep their bathers safe. Now go get'em tigers!
