प्रश्न
State the factors on which the strength of an electromagnet depends. How does it depend on these factors?
उत्तर
Strength of an electromagnet depends on following factors:
1. Number of turns in the coil:
By increasing the number of turns in the coil, the strength of electromagnet can be increased.
2. Current flowing through the coil:
By increasing the flow of current in the coil, the strength of electromagnet can be increased.
3. Length of air gaps between poles:
By reducing the length of air gaps between the poles, the strength of electromagnet can be increased.
