A permanent magnet is produced when
A) magnetic fields of large groups of individual atoms are permanently aligned.
B) electrons become stuck and cease to move.
C) electrical fields exchange electrons with the magnetic fields.

Question

Quizplus · Accepted Answer

Permanent magnets are made by aligning magnetic fields of individual atoms in a material such as iron, cobalt, or nickel. Through a process of magnetization, the magnetic domains of these individual atoms become permanently aligned, creating a magnetic field that does not require external energy to maintain.
