Question
The long, straight, and closely-wound solenoid shown in the figure below has length L = 0.560 m, 550 turns of wire and the radius of each turn is R = 1.50 cm. The solenoid is connected to a 64.0-V battery and the current I in the solenoid is 6.40 A. What are the magnitude in T and direction of the resultant magnetic field at a point inside the solenoid, near the center (point P)?

The solenoid is connected to a 64.0-V battery and the current I in the solenoid is 6.40 A. What are the magnitude in T and direction of the resultant magnetic field at a point inside the solenoid, near the center (point P)?Explanation / Answer
B=uo*N*I/L
B=(4pi*10^-7)*550*6.4/0.56
B=7.9*10^-3 T or 7.9 mT
