A ________ is a device that has a magnet on a needle that spins freely. It is used for navigation because its needle usually points north.

• calculator

• ruler

• compass

• map

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).

Which statement best compares the magnetic field of Earth to the magnetic field of a bar magnet?

• Magnetic field lines around Earth are symmetrical but magnetic field lines around a bar magnet are not symmetrical.

• Magnetic field lines around Earth are in a circular pattern but magnetic field lines around a bar magnet extend away from the magnet.

• Magnetic field lines for both Earth and a bar magnet are generated from convection currents.

• Magnetic field lines for both Earth and a bar magnet emerge from their north poles.

What is the direction of the magnetic field inside a solenoid?
