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)
