The magnetic field around a bar magnet can be plotted with ... .

• compass needles and a pencil

• a pencil and paper

• steel pins and a pencil

• thread and a compass needle

Brian had three rods, X, Y, and Z, of the same size but made from different metals.
The ends of each rod were labeled as shown below.

He brought different ends of the rods together in pairs, and recorded his observations as follows:
A repels F
B attracts C
B attracts D
D attracts E

Which rod(s) is/ are magnet?

• metal X only

• metal Y only

• all three metals

• metal X and Z

In the northern hemisphere one end of a compass needle points north. On the earth's equator which direction will this end of the compass needle point?

• East

• North

• West

• South

What term do we use when two magnets are pushing each other apart?

• Friction

• Attraction

• Repulsion

• Opposition

• One half would have a north and the other half would have a south pole

• each halfwould have its own north pole and south pole

• Neither half will be magnetized
