Are electromagnets used in generatorsto transform mechanical energy into electrical energy?
This requires magnets in general. It need not be an electromagnet; sometimes electromagnets are used, sometimes permanent magnets.
What do magnet have to do with simple motors?
Motors convert electrical energy to mechanical energy through moving electric conductors through a magnetic field. Magnets can be permanent magnets or electromagnets.
What is use of magnets?
One major use of magnets is to determine the direction. The other major use is to generate electricity. All generators make use of of permanent or electromagnets to convert Mechanical energy into Electrical energy.

How does electrical energy to mechanical energy take place in an electric motor?
The electricity is run through a coil of wire. This turns it into a magnet. Opposite poles attract and like poles repel. By arranging the coils on a rotating shaft, it can be made to pull the shaft around as it alternately gets attracted and repelled by magnets around the outside. Motors vary in construction, depending on voltage and use. Some have permanent magnets, with which to react with the coils. Others have no permanent magnets, but other separate coils, which have current running through them. The short answer is 'magnetism'.
What is a permanent magnet motor?
A motor with permanent magnets rather than field coilsA:A non-functional contraption often peddled as a free-energy generator.
Is magnetism consider a form of energy?
yes magnet is energy, surprisingly. magnets have at least one north pole and south pole, which make magnets have energy. Magnets provide energy. When you have two magnets and they are pushing against each other, that is how magnets provide energy. Magnets are better for the enviornment, because magnets are pollution-free.
Explain the term co-energy in magnetic system?
Coenergy is sort of a dual of stored energy that is often used to compute forces on systems with permanent magnets and current-carrying coils.
Where from permanent magnet get energy?
Permanent magnets don't get energy from anywhere. The nature of the atoms a natural magnet is made of allow for the free exchange of electrons with other objects that also have free electrons. Energy is conserved in the system, not used and so a natural magnet doesn't need power to operate.
How voltage build-up in a self-excited generator?
What can usually happen is the permanent magnets in the generator will become energized, and like static shocks, will store energy in them.
What type of energy repels magnets?
To create a permanent magnet energy must be supplied to suitable materiel by immersing it in a magnetic field normally supplied by an electromagnet
What do magnets need to be made?
energy
