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.
