Question

the magnetic force of a bar magnet is temporary meaning the magnetic field goes away true or false

Answer 1

False. The magnetic field of a bar magnet is considered a permanent magnetic field, meaning it does not go away unless the magnet is demagnetized or heated to a high temperature (curie point) where its magnetic properties can change. In contrast, temporary magnets (like those made from soft iron) will lose their magnetism when the external magnetic field is removed.
