Magnetic energy or magnetism is the force exerted between the two magnetic poles, producing magnetization. A magnetic field is an area around the magnet where magnetic or electrical force can be experienced and is a vector quantity which has both direction and magnitude.
Any object that can produce its own magnetic field is a magnet and the direction of magnetic field is the alignment of iron filings placed on a paper over a bar magnet. These imaginary lines are useful mathematical calculations and studies. Electrical currents also produce magnetic fields likewise magnetic fields also exert forces on moving electrical charges.
In fact electricity and magnetism are the same and are related by he two phenomena are related by Maxwell’s equations. Whereas electro magnetic energy will have both electrical and magnetic components and X rays, infra red rays, visible light and radio waves are all examples of electro magnetic radiation. Though these are basically electromagnetic rays their wavelengths and frequencies are different and hence behave differently. X rays are high frequency and short wavelength rays whereas microwave has longer wavelength and low frequencies.
One form of energy can be converted into another form by using converters like batteries or turbines. For instance in dry cells or batteries chemical energy is converted into electrical energy whereas in hydro electric dam potential energy is converted into electrical energy.
Magnetic energy is a good source of renewable energy, which can be recycled to meet the energy needs of the world without causing pollution and it can also be used for even household energy requirements and then recycle the energy back into the environment without producing pollution. The reputed car maker, “Peugeot’ has made use of the same polarity magnetic field application in designing its car, Magnet”. Magnetic energy is a great source of energy and a pollution free replacement for fossil fuels, which is the main reason for global warming and degradation of ecosystem.
