Residual electrical current in stainless steel strip




My friend is puzzled by his stainless device which after having DC power flowing through it (14 volts, 8 amps)for four seconds, retains a very slight current for two weeks. I cannot give away his purpose but the stainless is coiled closely to another strip of the same material.

Has the flow of electrons created a small, temporary, magnetic field? Whatever grade stainless it is, a magnet will not stick to it at all.

Hi, John.

Please look into the subject of "electrolytic capacitors" and see how closely your friend's device may resemble one. Good luck.

I am of the same opinion as Ted. The only solution is to ground it out as soon as the electricity quits flowing. Or reverse the current for a millisecond.
