Question

1. what is true about a ferromagnetic material? (1 point)

it can gain or lose magnetism.
its north pole is stronger than its south pole
its magnetic domains are constantly aligned.
it has only one pole.

Explanation:

Ferromagnetic materials can gain magnetism when exposed to a magnetic field (become magnetized) and lose magnetism when the external magnetic influence is removed (e.g., by heating above the Curie temperature). Magnetic poles of a magnet (including ferromagnetic - based magnets) are equal in strength (so the "north pole stronger" option is wrong). Magnetic domains in ferromagnetic materials are not constantly aligned - they align when magnetized. All magnets (including those made of ferromagnetic materials) have two poles (north and south), so the "only one pole" option is wrong.

Answer:

It can gain or lose magnetism.
