29. Sources of Magnetic Field
Magnetic Field Produced by Loops and Solenoids
A 300-turn solenoid used in an electronic device has a length of 15.0 cm and a cross-sectional area of 0.200 cm2. The wire used for the solenoid supports a maximum current of 60.0 A. Determine energy stored in the uniform magnetic field of the solenoid at maximum current.
