Application task (You do)
1

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.
