in the \before\ image, two bar magnets are positioned so their
north poles are side-by-side. in the \after\ image, one of the
magnets has been rotated. how will this affect the magnetic forces
between them?
a the forces get weaker
b the forces do not change
c the forces repel instead of attract
d the forces attract instead of repel

Explanation:

Magnetic poles follow the rule: like poles repel, opposite poles attract. Initially, the two bar magnets have North poles side-by-side (like poles), so they repel. When one magnet is rotated, its poles are flipped relative to the other magnet, meaning opposite poles are now aligned, so the force becomes attractive instead of repulsive.

Answer:

D. The forces attract instead of repel
