Answer:
Option 3, The attraction between the can and the magnet is a pull.
Explanation:
The complete question is
Mr. Wang works in a recycling center. Recyclable materials arrive at the
center mixed together. Workers use magnets to separate steel cans from
other items. Which two statements are true about the force between a steel can and a magnet?
1 Gravity pushes the can toward the magnet.
2 The force between the can and the magnet is a noncontact force.
3 The attraction between the can and the magnet is a pull.
4 The attraction between the can and the magnet is a push
Solution
The force exerted by magnet on steel is the pull force. In magnets unlike poles attract each other (pull force) while the like poles repel (push force). Now, the steel or any ferrous object in the garbage when experience magnetic field develop magnetic field of their own in such a way that their north always faces the south of the external magnet or vice versa.
Hence, the force between a steel can and a magnet is pull force
