Question

List the various methods of making a magnet.

Answer 1

Methods of magnetizing a magnetic material are :

1. Single-touch method: A magnet is stroked from one end to the other along the magnetic substance.

2. Double-touch method: At the centre of the magnetic substance, the opposite poles of two magnets are put next to each other and stroked in opposite directions.

3. Induction magnetizing:

1. This is a technique for creating temporary magnets under the influence of a magnetizing force.
2. When the magnetizing force's influence is eliminated, the magnetic qualities vanish.
3. (A permanent magnet is brought close to but not contacted with the magnetic substance).

4. Electromagnet:

1. An electromagnet is a magnet that is powered by electricity.
2. It's a transient magnet that ceases acting like one once the current is turned off.
3. When certain materials, such as steel and specific alloys, are put in a coil and a very strong current is run through it,
4. electromagnets can become permanent magnets.
