Describe two methods for creating a magnet.
What will be an ideal response?
A very powerful temporary magnet can be made by placing a bar of soft steel inside a coil of wire carrying an electrical current . This is an electromagnet. The intense magnetic force created is reduced to a weak residual force as soon as the current is interrupted. Magnetic materials also can be magnetized by placing them near a magnet. The magnetism produced in the material by this method is called induced magnetism. In the case of soft steel, the effect is only temporary. The magnetism is lost as soon as the magnet is removed.
