Magnetism is the attractive or repulsive force found between two objects, most often made of Fe or S.
Magnetite is a naturally occurring mineral that hasmagnetic properties.
Every magnet has two poles – a north and a south.Like poles repel and unlike poles attract.
The area through which this attractive or repulsiveForce is observed is called a magnetic field.
The earth, which produces a strong electric currentwithin the hot liquid outer core, produces an electricfield which we call the north pole.
