Question

The tiny magnetic effect of atoms within a domain is due to electrons that are

a. paired and spinning in opposite directions
b. unpaired and spinning in the same direction
c. unpaired and spinning in opposite directions
d. not spinning

Answer 1

D) all of the unpaired electrons spinning in the same direction.

Step-by-step explanation:

D) all of the unpaired electrons spinning in the same direction.

Answer 2

For magnetic effect, electrons must be unpaired and spin in same direction.

If electrons are spinning in same direction, they'll pair and hence no magnetic field will generate.

Hence in your question, they must be of same spinning to avoid pairing.

Hope this helps!
