How much energy is in a magnet?

  • by

To find the energy in a magnet, we calculate its magnetite content, which includes two primary elements — iron and cobalt — of the iron-nickel alloy used in most magnets and alloys. The amount of metal in the iron-nickel alloy depends on the magnet’s polarity.

In one specific case, the amount of energy in a magnet is calculated using a theoretical formula to find the total magnetic moment in the center. However, when the same calculation is applied to an ideal magnet, the results are often significantly different from what is seen in real life.

Energy in the center of an ideal magnet

If you place two magnets near each other, the centers of the magnets will touch. The energy in the center of a magnet is approximately 0.9 volts, but the magnet can be made to vibrate with no energy at all.

What energy does a magnet contain?

To find the energy contained in a magnet, we also have to know the ratio of its magnetic moment to its core’s potential energy. You need to find the ratio between the center of the magnet and the bottom of the magnet that is close enough to the center of the magnet to give you a direct measure of the energy contained there.

The energy in a magnet’s surface

Although the magnet’s magnetic moment is very small relative to the surface area of the magnet, magnetite does contain tiny amount of energy in the surface. The magnetic moment of a magnetite-containing magnet is less than the magnetic moment of the top of the magnet. The surface area will be smaller than in the case of the same magnet if the distance between the bottom and the magnet is the same as the distance between the poles of a magnet.

The strength of the Earth’s magnetic field

The journey to Nikola Teslas dream of free energy for everyone.
The area of a magnet’s surface is measured in terms of magnetic flux, a measure of the strength of the Earth’s magnetic field. This field varies with latitude and is greatest at the poles. You need to find the field strength at the points of the magnet that are closest to the center of the magnet so you can calculate the earth’s magnetic field strength at those points.

Magnetization coefficient

The magnetization coefficient measures the size of the magnetic field at the poles of a magnet in each of its three “poles of the earth” (see Figure 5 on page 4 of the Magnet Index of Earth’s Magnetic Elements). The larger the value in the figure, the larger the magnetic field, and
