Question

what is a magnetic compass? what are its applications? how can u make your own magnet​

Answer 1

The magnetic compass was an important advance in navigation because it allowed mariners to determine their direction even if clouds obscured their usual astronomical cues such as the North Star. It uses a magnetic needle that can turn freely so that it always points to the north pole of the Earth's magnetic field.

Making own Magnet

Take an Iron bar and a Magnet bar.

Place one of the magnet's pole at the edge of the iron bar.

Slide the magnet towards the other edge of the iron bar without lifting the magnet.

Lift the magnet now and place at the initial position again with same pole touching iron bar.
