Strength of electromagnet depends on:
(i) The number of turns in the coil: Increasing the number of turns in the coil increases the strength of the electromagnet.
(ii) The current flowing in the coil: Increasing the current flowing in the coil increases the strength of the electromagnet.
(iii) The length of air gap between its poles: Reducing the length of air gap between the poles of electromagnet increases the strength of the electromagnet.
