Magnet Power Calculator

The Magnet Power Calculator allows you to calculate the magnet power (in watts) using inductance, current, and time.

Formula Explanation

The magnet power is calculated using the following formula:

\[ P_m = \frac{1}{2} \times L \times \frac{I^2}{dt} \]

Where:

• \( P_m \) is the magnet power (watts).
• \( L \) is the inductance (henries).
• \( I \) is the current (amps).
• \( dt \) is the time (seconds).

Example Calculation

For example, if the inductance is 2 henries, the current is 3 amps, and the time is 4 seconds:

\[ P_m = \frac{1}{2} \times 2 \times \frac{3^2}{4} = 2.25 \text{ watts} \]

This calculator is particularly useful for engineers and physicists working with electromagnetic systems.
