Theory?

I have a theory, that if a magnetic field dissipates at a rate of x m/s,
then having a second magnetic field to replenish it at ½ x/s, then the
magnetic field will remain constant, and may in fact, be increased, even
though both magnetic fields have relatively the same rate of decay...

Can someone confirm or deny this for me pls? I would do an experiment
myself, except I'm lazy =/ lol

Also, if the magnetic field is replenished this way, what effect would
it have on metals and other magnetic objects, and what effect would it
have on non-metals and other non-magnetic objects?

BTW: I'm an n00b, so the terms I have used I have used because they make
sense to me.

Any help would be helpful

Thanks.
