Detailed explanation-1: -A permanent magnet is one that retains its magnetic properties for a long period of time. Examples are iron, nickel, cobalt and some rare earth alloys etc. Temporary magnets are those that simply act like permanent magnets when they are within a strong magnetic field.

Detailed explanation-2: -Temporary magnets can be created by rubbing an item containing iron in a single direction with a permanent magnet. Temporary magnets can also be created when an electric current flows through a wire. This temporary magnet is called an electromagnet.

Detailed explanation-3: -A temporary magnet is a magnet made of soft iron, that is usually easy to magnetize; however, temporary magnets lose most of their magnetic properties when the magnetizing cause is discontinued.

Detailed explanation-4: -A temporary magnet is only able to create its own magnetic field while in the presence of a stronger magnet. In other words, these types of magnets need assistance from a larger force in order to be able to attract other objects and magnets.
