Question

The magnetic field inside an air-filled solenoid 32.7cm long and2.50cm in diameter is 0.700T. Approximately how much energy isstored in this field?

Answer 1

Answer #1

Formula for calculating the value of the energy stored in themagnetic field is

Here B = 0.700T
A =

l=0.327m
Substitute all the given values in the above formula we get thevalue of the energy stored(U).

The magnetic field of a long thin solenoid is approximately zero outside the solenoid and a uniform Bsol inside the solenoid. A square conducting frame is located as shown. The large frame is located entirely outside the solenoid while the small frame is located entirely inside the solenoid. The frame and solenoid are oriented so their axis coincide. What is the magnetic flux through the square frame? A. Bsol times the area of the frame for the top case and...
