Question

based on the magnetic field lines in the diagrams, what will happen next with these two sets of magnets?
in both sets, the magnets will attract.
the magnets in set 1 will attract, the magnets in set 2 will repel.
the magnets in set 1 will not move, the magnets in set 2 will attract
the magnets in set 1 will repel, the magnets in set 2 will attract.

Explanation:

Magnetic field lines: For repulsion (like poles, e.g., north - north or south - south), field lines push apart; for attraction (unlike poles), field lines connect. In Set 1, field lines between magnets show repulsion (lines don't connect, push), in Set 2, lines connect, so attraction.

Answer:

The magnets in Set 1 will repel, the magnets in Set 2 will attract.
