Describe the methods used to make magnets. Use diagrams where necessary.

Answers

The following are methods used to make magnets.
a) Magnetic induction – this is a process by which magnets are made by placing
ferromagnetic materials in a magnetic field. Materials like iron lose their magnetism easily and are said to be soft while others like steel gain magnetism slowly but retain it
longer and are therefore said to be hard and are used to make permanent magnets.
b) Magnetizing by stroking – the object to be magnetized is placed on a bench then a bar
magnet is dragged along the length of the bar from one end to the other. This is repeated
several times and the object becomes magnetized. This method is known as single-stroke method.

c) Magnetizing using an electric current – this is the use of magnetic effect of an electric
current through a solenoid (insulated wire of many turns)
