Magnetic Forces and Fields

What would happen when two north poles of magnets are placed together?

• The force will pull them together (attract).

• The force will push them away from each other (repel).

• The strength of the magnet is doubled.

Where is the force of attraction the strongest on a magnet?

• above the magnet

• below the magnet

• at the poles

• Increases
• Decreases
• Stays the Same

Are the magnetic field lines in the picture correct?

• Yes, because they point from north to south.
• No, because they point from north to south (they're supposed to go the other way).
• Yes, because the North pole is on the left in all pictures.
• No, because the North pole is on the left in all pictures (it's supposed to be on the right).
