I think you're fishing for "temporary magnet" or something like that,
but I don't agree with it.
Credit card strips, refrigerator magnets, recording tape, bar magnets,
and big heavy horseshoe magnets are permanent magnets ... you don't
have to keep an electric current circulating around them to make them

floor, hit with a hammer, or in the presence of another, stronger magnet.

Mass is not a force, its unit is given usually in kilogram [kg]
