a.) A solenoid is producing a magnetic field of B = 5.5 x 10-3 T. It has N = 1300 turns uniformly over a length of d = 0.15 m.
Randomized Variables
B = 5.5 x 10-3 T
N = 1300 turns
d = 0.15 m
Express the current I in terms of B, N and d.
Calculate the numerical value of I in amps.
b.) A solenoid is made of N = 4500 turns, has length L = 15 cm, and radius R = 1.1 cm. The magnetic field at the center of the solenoid is measured to be B = 4.9 x 10-1 T.
Randomized Variables
N = 4500 turns
L = 15 cm
R = 1.1 cm
B = 4.9 x 10-1 T
