What is the value of the energy of the magnetic field of a coil with an inductance of 0.5 H with a current in it of 4 A?
| April 24, 2021 | education
Initial data: L (coil inductance) = 0.5 H; I (coil current value) = 4 A.
The value of the magnetic field energy of the coil current can be determined by the following formula: Wm = L * I2 / 2.
Let’s calculate: Wm = 0.5 * 4 ^ 2/2 = 4 J.
Answer: The value of the magnetic field energy of the coil current is 4 J.
