Question

Three magnets are tested by attaching paper clips to the north pole. Magnet A holds six paper clips.

Magnet B holds five paper clips, and Magnet C holds two paper clips. Magnets A and C are warmed in
the oven for a few minutes and then retested. Now, Magnet A holds only four paper clips, Magnet B st
holds five paper clips, and Magnet C cannot hold any paper clips. Which statement explains the
changes?
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,
in change dine

Answer 1

The heating of the magnets likely caused some magnetic domains within Magnet A and Magnet C to become unaligned, reducing their magnetic strength, as evidenced by the decrease in the number of paper clips they could hold after being warmed.

Step-by-step explanation:

The observed changes in the magnetic strength of the magnets after they were heated can be explained by the effect of temperature on the alignment of magnetic domains within the magnets. When magnets are heated, the increased thermal energy can cause some of the magnetic domains to become unaligned, which reduces the overall magnetic strength of the magnets.

Warming a magnet indeed causes some of the magnetic domains to misalign, thereby diminishing its magnetic force. This is demonstrated by Magnet A and Magnet C which, after being heated, held fewer to no paper clips, respectively. Magnet B, which was not heated, maintained its magnetic strength, further supporting the conclusion that heat disrupted the alignment of magnetic domains.

When conducting experiments with paper clips and magnets, if you rub a paper clip with a magnet, it becomes temporarily magnetized due to the alignment of its domains in the direction of the magnetic field. This temporarily magnetized paper clip can then attract other paper clips, showing attractive forces.
