The magnitude of the magnetic field inside the solenoid is .
The given parameters;
- <em>length of the solenoid, L = 91 cm = 0.91 m</em>
- <em>radius of the solenoid, r = 1.5 cm = 0.015 m</em>
- <em>number of turns of the solenoid, N = 1300 </em>
- <em>current in the solenoid, I = 3.6 A</em>
The magnitude of the magnetic field inside the solenoid is calculated as;
where;
is the permeability of frees space = 4π x 10⁻⁷ T.m/A
Thus, the magnitude of the magnetic field inside the solenoid is .
