Magnetic Energy Formula
The following equation is used to calculate the Magnetic Energy.
Em = .5 * L * I ^2
Variables:
- Where Em is the Magnetic Energy (Joules)
- L is the inductance (Henries, h)
- I is the current (amps)
How to Calculate Magnetic Energy?
The following two example problems outline the steps and information needed in order to calculate the Magnetic Energy.
Example Problem #1:
- First, determine the inductance (Henries, h). In this example, the inductance (Henries, h) is measured to be 10.
- Next, determine the current (amps). For this problem, the current (amps) is calculated to be 2.
- Finally, calculate the Magnetic Energy using the formula above:
Em = .5 * L * I ^2
Inserting the values from above and solving the equation with the imputed values gives:
Em = .5 * 10 * 2 ^2 = 20 (Joules)
Example Problem #2:
Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:
inductance (Henries, h) = 20
current (amps) = 3
Entering these values into the formula or calculator above gives us::
Em = .5 *20*3 ^2 = 90 (Joules)
