State the factors on which the strength of an electromagnet depends. How does it depend on these factors ? |
|
Answer» 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 |
