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:

First, recall magnetic pole rules: like poles repel, opposite poles attract. In the "Before" setup, two North poles are adjacent, so the magnets repel each other. In the "After" setup, one magnet is rotated so a South pole is next to the North pole of the other magnet, creating an opposite pole pair. This changes the interaction from repulsion to attraction.

Answer:

D. The forces attract instead of repel
