Enter the inductance (h), the current (amps), and the time (s) into the calculator to determine the Magnet Power.

## 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

1. First, determine the inductance (h). In this example, the inductance (h) is determined to be 10 .
2. Next, determine the current (amps). For this problem, the current (amps) is measured to be 3 .
3. Next, determine the time (s). In this case, the time (s) is found to be 50.
4. 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)
