Question

A student places two horseshoe magnets next to each other, and the poles of the magnets attach to each other. How does the kinetic energy of the system change?(1 point)

Kinetic energy decreases because the magnets move in the direction of the field.

Kinetic energy increases because the magnets move in the direction of the field.

Kinetic energy increases because the magnets move in the opposite direction of the field.

Kinetic energy decreases because the magnets move in the opposite direction of the field.

Answer 1

Kinetic energy increases because the magnets move in the direction of the field.

Explanation: Opposite poles attract, so magnetic potential energy is converted into kinetic energy as they move together along the field lines, increasing the system's kinetic energy.
