What conclusion did Arthur Compton make about ferromagnetism?
It was a result of the alignment of electron spins
It was a result of the wave nature of light
It was due to gravitational pull
None of the above
Answer
Ferromagnetism is a result of the alignment of electron spins. In other words, the magnetic properties of a material are determined by the way its electrons are spinning. When the spins of a majority of electrons are aligned in the same direction, the material exhibits ferromagnetism.
