A28 cm long solenoid 1.25 cm in diameter is to produce a field of 0.353 t at its center. how much current should the solenoid carry if it has 97 turns of the wire?

810.9 A

Explanation:

Length of the solenoid = 28 cm =0.28 m

Magnetic field B =0.353 T

Number of turns N =97

We know that the magnetic field due to solenoid where

So

Current i =810.9 A

So the current in the solenoid will be 810.9 A

thermal energy is the answer
