Question

Give two methods by which we can increase the strength of magnetic field produced by a circular coil carrying current?​

Answer 1

Answer:

forcely by increasing the current vector there will be increase in the magnetic field.

Secondly if the number of turns of the coil per unit length is increased then there will be increase in strength of the magnetic field.

this is because with change their will be changed in the amount of flux that is used in production of the magnetic field. This concept is used in making electromagnet of different strength

Explanation:

Answer 2

Answer:

The strength of the magnetic field around a solenoid can be increased by: increasing the number of turns on the coil. increasing the current.
