Question

Jesse tests three magnets by observing how many paper clips he can attach to the north pole in a single chain. He finds that Magnet A holds six paper clips, Magnet B holds five paper clips, and Magnet C holds two paper clips. He warms Magnets A and C in the oven for a few minutes and repeats his procedure. This time, Magnet A holds only four paper clips, Magnet B still holds five paper clips, and Magnet C cannot hold any paper clips. Which statement explains Jesse’s observations?

A. Warming a magnet unaligned some of the magnetic domains.

B. The forces produced by a magnet naturally become weaker over time.

C. Warming a magnet causes the distance of its magnetic force to decrease.

D. The poles of the magnet become reversed when warmed and cause it to repel the paper clips.

Answer 1

a

Step-by-step explanation:

When exposed to hotter conditions, the particles within the magnet are moving at an increasingly faster and sporadic rate. This misaligns the particles, causing the magnetism to be lost.
