Background For Teachers:
If the north end (N) of a bar magnet is held close to a compass, the south end (S) of the compass will be attracted to it. The same holds true when the south end (S) of a bar magnet is held close to the north end (N) of a compass. When a magnet is brought close to a compass, the magnet 's magnetic field overrides Earth 's effect on the needle. When the magnet is taken away, Earth's magnetic field affects the compass once again.
Intended Learning Outcomes:
Invitation to Learn:
Glue thread to a magnet ball and suspend in mid-air. When the ball has stopped turning, mark the side "N" that is facing north. Paint that side of the ball white. Suspend the ball in mid-air. Stand in place and turn in a circle. What do you observe? Walk around the room with the ball suspended in mid-air. What do you observe?
Experiment to see what other things might be magnetized to become compasses, (e.g., nail, paperclip, screws, nuts, different types of wire).
