Question

1. this is a diagram of two bar magnets.

magnet x: n (left), s (right); magnet y: n (left), s (right)
what will happen to these two magnets?
a. they will move closer together.
b. they will move apart.
c. magnet y will move in a circle.
d. magnet x will move in a circle.

1. a bar magnet has been cut into four pieces of equal length and width. what is the pole strength of each piece compared to the pole strength of the original bar magnet?

a. double, because the magnetic domain only depends on the width of the magnet

Explanation:

For question 11: The adjacent poles are the south pole of Magnet X and the north pole of Magnet Y. Opposite magnetic poles attract each other, so the magnets will move closer.
For question 12 (partial): When a bar magnet is cut into smaller equal pieces along its length/width, each piece becomes a smaller magnet with weaker pole strength than the original. The pole strength is reduced because the total magnetic material is divided, and each piece has less magnetic dipole moment. (Note: The full options for question 12 are not visible, but the core principle is that each piece has lower pole strength than the original.)

Answer:

1. A. They will move closer together.
2. (Full answer requires complete options, but based on physics principles: Each piece has a pole strength less than the original bar magnet.)
