A horseshoe magnet is moved toward a pile of iron shavings. The iron shavings divide and attach to both ends of the magnet. How does the kinetic energy of the system change? (1 point)

Responses

a Kinetic energy decreases because iron shavings move in the opposite direction of magnetic force. 

b Kinetic energy increases because iron shavings move in the direction of magnetic force. 

c Kinetic energy decreases because iron shavings move in the direction of magnetic force. 

d Kinetic energy increases because iron shavings move in the opposite direction of magnetic force.
