A current passes through this solenoid from the left to right end. How should the magnetic field arrows be drawn?

• The magnetic field arrows should be drawn inward at both ends

• The magnetic field arrows should be drawn outward at both ends

• The magnetic field arrows should be drawn into the left end and out of the right end

• The magnetic field arrows should be drawn into the right end and out of the left end

Look at this solenoid. How would a permanent magnet stood underneath the solenoid be affected?

• A permanent magnet stood under this solenoid with the south pole upwards would be attracted

• A permanent magnet stood under this solenoid with the south pole upwards would be repelled

• A permanent magnet stood under this solenoid with the north pole upwards would be repelled

• A permanent magnet stood under this solenoid with the north pole upwards would be unaffected
