Answer

Brief Explanations:

A magnetic field is the area around a magnet where magnetic - force can be detected. Atoms lined up inside a magnet are related to the magnet's internal structure, not the definition of the magnetic field. And a magnetic field has nothing to do with temperature changes caused by magnetic materials.

Answer:

B. A magnetic field is a region of magnetic force around a magnet.
