What is the energy of the magnetic field of a coil with an inductance of 2H at a current strength of 200A.
| January 26, 2021 | education
The magnetic field energy of a given coil can be calculated using the following formula:
Wm = L * I ^ 2/2, where L is the given inductance of the coil (L = 2 H), I is the given current in the coil (I = 200 A).
Let’s make a calculation:
Wm = 2 * 200 ^ 2/2 = 40,000 J = 40 kJ.
Answer: The energy of the magnetic field of a given coil is 40 kJ.
