Howard, what do you suppose would happen to the magnetic strips on my credit cards if I rode in your car with the rare earth magnets in the seats?
I don't know for sure and have been giving that some thought. The magnets I'm considering have the field concentrated at the ends and are supposed to have a very low spill to the sides. The strength does diminish with distance so that's a help.
They will be enclosed in the aluminum hinge which should shield some. Since these magnets are somewhat brittle, am also thinking of supporting them and shielding more by sliding them into a stainless steel tube. All I need is for them to attract end to end.
Hoping the magnets work but if leakage turns out to be a problem, guess I could probably come up with a few of the caution signs we used to hang on the MRI suite doors. Black and yellow might clash with my car though. Could have a wallet safe box hanging on the outside of the car.
