In summary, making a material magnetic does not create potential energy, but rather allows it to be affected by the magnetic field of other objects through the conversion of magnetic potential energy to kinetic energy.

When you "make" a magnet is PE created?

Okay my understanding of a magnet is that if a magnetic material is placed in it's field then the Magnetic Potential Energy is converted to Kinetic Energy in the object and thus you get the attractive force and movement in the object which subsequently reduces the Potential Energy the field has on the object. That is all fine and dandy but what happens if you make a material magnetic? Does it all of a sudden create a potential for all other magnetic objects to lose energy in the form of kinetic?
Cheers,

No, making a material magnetic does not create potential energy. Making a material magnetic simply causes it to be affected by the magnetic field of other objects, and so it can move in response to that field. This movement is caused by the kinetic energy of the material, but no potential energy is created.
 

1. How is potential energy (PE) created when making a magnet?

When making a magnet, potential energy is created through the alignment of magnetic domains within the material. This alignment occurs when an external magnetic field is applied to the material, causing its atoms to line up in a specific direction. This results in a buildup of potential energy within the material, which can then be released as kinetic energy when the magnetic field is removed.

2. What factors affect the amount of PE created when making a magnet?

The amount of potential energy created when making a magnet depends on several factors, including the strength of the external magnetic field, the type of material used, and the temperature at which the magnet is created. Generally, stronger magnetic fields and materials with higher magnetic permeability will result in a greater buildup of PE.

3. Can the amount of PE in a magnet be increased or decreased?

Yes, the amount of potential energy in a magnet can be increased or decreased by changing the external magnetic field or altering the material's properties. For example, increasing the strength of the magnetic field or using a material with higher magnetic permeability will result in a higher amount of potential energy, while decreasing the magnetic field or using a less magnetically permeable material will result in a lower amount of potential energy.

4. What happens to the PE in a magnet when it is used in an electrical circuit?

When a magnet is used in an electrical circuit, the potential energy is converted into kinetic energy as the magnetic field interacts with the electrical current. This kinetic energy can then be used to perform work, such as rotating a motor or generating electricity.

5. Can the PE in a magnet be completely depleted?

No, the potential energy in a magnet cannot be completely depleted. Even when the external magnetic field is removed, the magnet will still retain some of its potential energy due to its alignment of magnetic domains. However, this potential energy can be significantly reduced by demagnetizing the magnet, which involves heating it to a high temperature or subjecting it to a strong opposing magnetic field.
