Answer:
Single touch method is one of various ways of making a magnetic material like soft iron into a magnet. ... When a bar magnet is brought near a magnetic material like iron, steel it gets attracted towards and sometimes gets lifted by the magnet if the material density is less. This is called Single touch method.
Double touch:
Magnetization by Double Touch. The process of magnetizing a steel bar by simultaneously stroking it with two poles of a horseshoe magnet or with two opposite poles of two bar magnets. The poles must be close but not touching. A block of wood may be placed between the ends if single magnets are used.
