An air-core solenoid with 63 turns is 8.00 cm long and has a diameter of 1.20 cm. How much energy is stored in its magnetic field when it carries a current of 0.780 A? (answer in µJ)© BrainMass Inc. brainmass.com December 24, 2021, 5:04 pm ad1c9bdddf
^ denotes power
E-06 means 10^ (-6)
Diameter of the solenoid=d= 1.2 cm= 0.012 m
Length of solenoid=l= 8 cm= 0.08 m
Volume of the solenoid=V= pi d^2 l /4= 9.0478E-06 m^3
