An example is the energy in the magnetic field round an inductor carrying a direct current. The energy is ½Li2 which in words is 'a half times L time i-squared' - sorry but the superscript font isn't working and hasn't been fixed in months . . . L is the inductance and i is the current.
When James Clerk Maxwell thought up circuit theory in the 1860s he decided to treat electric-field energy as potential energy and magnetic-field energy as kinetic energy, and then apply a mathematical method normally used for mechanical systems (Lagrange's equations). From that came the basics of circuit theory we use today.

What kind of energy does a compass use?
Magnetic energy
What is a example of converting electrical energy into magnetic energy?
An electromagnet, a coil of wire round a magnetic core. An electric current in the wire produces a magnetic field round the core, which contains energy which could be used to lift a load.
What happens with the energy associated to the magnetic field of a coil with electric current if the electric current is turned off?
The magnetic field or energy associated with the magnetic field will no longer be generated if the current is turned off.
For a permanent magnet where is the energy associated to the magnetic field of the magnet stored?
For both the magnetic and electric (static) fields, energy is considered to be stored in the field.
What is the purpose of a magnetic field?
This field is called magnetic flux. They are created by eddy currents from the coil itself and the energy running through it. This is where the energy of magnet is stored. You tap that energy to create power or hold objects that have a ferrous base.
How much energy is produced by electro magnetic?
This is dependent on: 1. The construction of the Magnet...materials, size, design. 2. The amount of CURRENT flowing through it.
Is there magnetic energy in the universe?
yes there is a magnetic energy in the universe
What is the problem associated with magnetic energy?
what are the problems associated with magnetic energy.
How do you make magnetic energy?
Magnetic energy is made by the connection of 2 magnents
Is magnetic a type of energy?
It takes some energy to build up a magnetic field; when the magnetic field collapses, the same amount energy is released again. So, it makes sense to consider that somehow, energy is stored in the magnetic field.
What is used for magnetic energy?
Magnetic energy is now being used to power some homes.
What is magnet energy a part of?
Magnetic energy.
What is the amount a wave dependent on?
An energy wave is dependent on the energy input and the composition of the medium in which it moves.
Can you create energy with magnetic force?
Yes, an electrical generator uses magnetic fields to transfer mechanical energy into electrical energy.
What energy transfers take place in a magnetic compass?
magnetic
Does sun have magnetic energy?
no, only our earth has the magnectic energy The Sun has a very strong magnetic field.
What wave consists of a combination of electrical and magnetic energy?
Electromagnetic waves consist of electrical and magnetic energy.
