True or False: If a needle is magnetized by holding it perpendicular to a bar magnet’s north pole, the needle can be used as a compass needle
Homework Answers
Answer: True
If a needle is magnetized by holding it perpendicular to a bar magnet’s north pole, the needle can be used as a compass needle.
Molecules of magnetic materials (needle) behaves like tiny magnets. Each of these tiny `magnetic particles' has two poles. Normally these tiny magnets are in random orientations. So their polarity neutralizes and material does not have any magnetic property. When the needle is magnetized the tiny molecular magnets gets lined up with their north poles pointing in one direction and south poles pointing in other direction, making its magnetic property effective.

1-A compass is held horizontally. The silver end of the needle
points towards geographic south and the blue end points towards
geographic north. The compass is then brought near one pole of a
horseshoe magnet. The blue end of the compass points towards this
pole. What is the polarity of this pole on the magnet?
