How to Use the Magnetic Energy Calculator
Using the Magnetic Energy Calculator is straightforward:
- Measure Inductance (L): Determine the inductance of the coil or inductor, typically measured in Henries (H). Inductance represents the ability of an inductor to store energy in its magnetic field.
- Measure Current (I): Find the current flowing through the inductor, measured in Amperes (A). This current will influence the amount of energy stored in the magnetic field.
- Input Values: Enter the values for inductance and current into the calculator.
- Calculate Magnetic Energy (Em): The calculator uses the formula:
Em = 0.5 × L × I²
This formula computes the energy stored in the magnetic field. - Interpret the Result: The result will be displayed in Joules (J), representing the magnetic energy stored.
