What is an induced magnet?
What happens to an induced magnet when it is removed from the magnetic field?
3 different materials were placed near 3 identical bar magnets. Draw arrows either side of the objects to represent the direction of magnetic force, when each bar magnet is placed near the material
Explain your answer. (6)
3 different materials tested with bar magnets to see if they were magnets, magnetic materials, or non-magnetic.
•Material 1 showed no magnetic force and remained stationary when a either pole of a bar magnet was placed near it.
•Material 2 was attracted to only the north pole.
•Material 3 was attracted to both poles.
Name the types of materials and justify your answer. (6)
Nickle is a magnetic material
Only permanent magnets repel.
Magnets have a North and South Pole.
Identical poles attract.
Magnets have to be touching to affect each other.
