Magnet Power Calculator

Formula

To calculate the Magnet Power (Pm):

\[ Pm = \frac{1}{2} \cdot L \cdot I^2 / dt \]

Where:

\(Pm\) is the Magnet Power (watts)
\(L\) is the inductance (henries)
\(I\) is the current (amps)
\(dt\) is the time (seconds)

What is Magnet Power?

Magnet power refers to the power associated with an electromagnet, which is calculated based on the inductance, current, and time. This calculation is useful in various applications, including electrical engineering and physics, to determine the energy stored in an electromagnetic field.

Example Calculation 1

Let's assume the following values:

Inductance (L) = 0.5 H
Current (I) = 2 A
Time (dt) = 1 s

Using the formula:

\[ Pm = \frac{1}{2} \cdot 0.5 \cdot 2^2 / 1 = 1 \]

The magnet power is 1 watt.

Example Calculation 2

Let's assume the following values:

Inductance (L) = 1 H
Current (I) = 3 A
Time (dt) = 2 s

Using the formula:

\[ Pm = \frac{1}{2} \cdot 1 \cdot 3^2 / 2 = 2.25 \]

The magnet power is 2.25 watts.
