Question

How does strength of magnetic field near a circular coil carrying current be increased?

Answer 1

magnetic field is increases when current is increases becz magnetic field is directly proportional to current

magnetic field is increases when no. of terms of wire increase becz it is also directly proportional to No of terms

Answer 2

Answer:

i) By increasing the strength of the current passing though it.

ii) By increasing the number of turns.

iii) By reducing the radius of the coil.
