1. Single-touch method - A magnet is rubbed along the magnetic substance from one end to another.

2. Double-touch method - Opposite poles of two magnets are placed next to each other at the center of the magnetic substance and rubbed in opposite direction along it.

3. Magnetizing by Induction - It is a method to make temporary magnets under the influence of a magnetizing force. The magnetic properties disappear when the influence of the magnetizing force is removed.

4. Electric current — A magnet made by using electric current is called an electromagnet. It is a temporary magnet and stops behaving like a magnet when the current is stopped. Electromagnets can become permanent magnets if certain materials like steel and special alloys are placed in a coil and very strong current is passed through the coll.
