## Magnet Power Formula

The following formula is used to calculate the Magnet Power.

**Pm = 1/2 * L * I^2 / dt**

- Where Pm is the Magnet Power (watts)
- L is the inductance (h)
- I is the current (amps)
- dt is the time (s)

## How to Calculate Magnet Power?

The following example problems outline how to calculate Magnet Power.

**Example Problem #1**

- First, determine the inductance (h). In this example, the inductance (h) is determined to be 10 .
- Next, determine the current (amps). For this problem, the current (amps) is measured to be 3 .
- Next, determine the time (s). In this case, the time (s) is found to be 50.
- Finally, calculate the Magnet Power using the formula above:

Pm = 1/2 * L * I^2 / dt

Inserting the values from above and solving yields:

Pm = 1/2 * 10 * 3^2 / 50 = .9 (watts)

**Example Problem #2**

Using the same method as above, determine the variables required by the formula. For this example problem, these are:

inductance (h) = 13

current (amps) = 6

time (s) = 4

Enter these given values into the calculator or above yields:

Pm = 1/2 * 13 * 6^2 / 4 = 58.5** **(watts)
