A uniform magnetic field with a magnitude of 53.9 mT completely fills a cylindrical volume of space with a length of 26.6 cm and a radius of 1.02 cm.
Part (a) ✔
How much energy, in millijoules, is stored in the magnetic field in the given volume of space?
UM = 100.6 mJ
✓ Correct!
Part (b)
Suppose the cylindrical volume is the interior of an air-filled solenoid with a current 69.8 A through its windings. What is the inductance, in microhenr
solenoid?
