The magnetism of a magnet can be lost when the magnet is dropped primarily because A. its structural strength might become weakened.
B. it accelerates as it falls.
C. its compliance coefficients might become transformed.
D. its magnetic domains might become misaligned.
E. its chemical composition might become compromised.

A

Explanation:

Dropping the magnet its weaknging the structure

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
