What is true about electricity and magnetic fields?

• Electricity is needed to create any magnet.
• Electricity always creates a magnetic field.
• Electricity is stronger than a magnetic field.
• Electricity prevents magnetic fields from occurring.

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).

Based on the arrangement of the electric field lines in the diagram, what are the charges?

• both charges are the same

• the charges are opposite

• they are neutral; no charge
