The current in the coil is 1.0 A. What is the inductance of the coil if the energy of the magnetic field is 4.0 J.
December 29, 2020
We write the formula for the energy of the magnetic field Wm = (LI ^ 2) / 2, where L is the inductance, I is the current strength, it follows that L = 2Wm / I ^ 2 = 8/1 = 8H
