In this exercise we have to use the knowledge of magnetism to be able to explain, in this way we find that:

Is true.

So remembering some information about magnetism we have:

Magnetism happen extrasensory perception exerted by magnets when they draw attention or repulse each other. Magnetism happen bring into being apiece motion of electric charges. To enhance magnetized, another powerfully magnetic stuff must record the magnetic field of currents of an existing bait. The magnetic field of currents happen the area situated on sides a bait that has attractive force

So with this knowledge, we can say that:

Some artificial magnets will maintain their attractive characteristic forever*. These exist refer to as permanent magnets. Some will only exist drawing when in the ghost of an extrinsic magnetic field, in the way that from a lasting magnet.
