Types of magnetism are-
1. Diamagnetism- Diamagnetic material exhibits diamagnetism. It is a weak form of magnetism, in this material are not attracted to magnetic field. Diamagnetic material usually get repelled from magnet.
In this material forms magnetic field is opposite to externally applied magnetic force and is repelled by magnetic field.
2. Paramagnetism - Paramagnetic material exhibits para magnetism. It have most unpaired electrons. These material tends to get weakly magnetize in direction of magnetizing field when it is placed in the magnetic field.
These have a permanent magnetic and dipole moment.
3. Ferromagnetism - It have strong magnetic attraction even at a time of absence of external magnetic field. These area magnetize in direction field and are strongly attached to magnet.

What is a compass? How is a compass used to find directions?
Magnetic field lines never intersect each other because
There will be two directions of the field at the same point.
Feild lines repel each other
Field lines follow discrete paths only
If field lines intersect they create a new magnetic field within the existing fieldTwo parallel wires carry currents of 20 A and 40 A in opposite directions. Another wire carrying a current antiparallel to 20 A is placed midway between the two wires. The magnetic force on it will be
