What current is required in the windings of a long solenoid that has 1100 turns uniformly distributed over a length of 0.410 m to produce at the center of the solenoid a magnetic field of magnitude 1.00 ✕ 10-4 T?
Homework Answers
Magnetic field in a solenoid = uo NI/L
where N = number of turns
I = current , L = length of solenoid
10^-4 = 4pi*10^-7*1100*I / 0.41
I = 0.0296 A
current in the windings is 29.6 mA
