Magnetic fields are generated by permanent magnets, electromagnets, and changing electric fields. Energy is stored in these magnetic materials to perform work and is different for different materials. Since it is stored energy, magnetic energy is a form of potential energy. Scottish mathematician and scientist James Clerk Maxwell are credited with having discovered magnetic energy during his pioneering work on electromagnetism in 1865.
How is Magnetic Energy Calculated
Examples and Uses
Magnetic Energy and Electric Energy
The total energy, E, is the integral of ρm over a given volume. Which gives the following expression: Where, H: Magnetic field strength B: Magnetic field μo: Permeability of free space L: Inductance I: Current Unit: Joules or J
