Magnetic energy and electric energy are virtually the same according to Maxwell's equations.
Which shows maxwell doesnt know what he is talking about then, they are two very distinc energies. Im not sure myself about the ways to convert them I am looking into it at this very moment.
Electromagnets.
generator
Toasters, electric heaters, and hair dryers are just a few devices that convert electrical energy to thermal energy.
example of devides that can convert to elecrical energy
There is no such thing as "electronic energy". Electronic devices use normal electrical energy.
answer
Photo voltaic cells (solar cells) convert light energy into electrical energy. Electric generators convert kinetic energy into electrical energy. Internal combustion engines convert chemical energy into kinetic energy.
Electrical energy is converted to sound energy in loudspeakers and earphones. The basic internal transducers are either magnetic coils or piezo-electric crystals.
The usual method to convert mechanical energy into electrical energy is to move a wire in a magnetic field (or alternately, move the magnet near to a wire).
I assume you mean magnetic energy. There is not much to convert there. A magnet doesn't store large amounts of energy. And especially, it is not an energy source - whatever energy you get out of it, you have to put in first.
The motor does it, by producing a rotating magnetic field, which twists the fan blades.
This is done with a so-called "generator". It uses the interactions between electricity and magnetism to convert the movement to an electrical current. That is, if a conductor moves through a magnetic field, a voltage is induced.
