Hello
I am new member
I want to know the expected time for an electromagnet to lose its magnetism if we put a diode "snubber". I know it depends on the number of turns and the current through its wire. But I suggest that 200 truns, 0.5 Amps current, radius of 1 cm and length of 5 cm is enough to do its job.

I am waiting your reply.

 

The decay time may be estimated by the ratio, L/R x 5. The inductance (L) will vary, however by the iron that is attached to the magnet. You can watch the decay time on a scope, if you have one.
