Electric motors and electric generators can have permanent magnets or electromagnets. It depends on the design. For example electric generators can be dynamos, alternators, or rotary converters. However, in General Electric motors are electromagnetic so that resistance disappears when current is cut and electric generators have permanent magnets.

∙ 10y agoYes they both use a magnetic field to produce a force on a current-carrying conductor.
DC motos and generators are the same thing. You can run a motor off a battery, but if you crank it faster than it wants to go, by using some kind of engine, power will then flow back into the battery and the motor has become a generator.

∙ 11y agoThe difference is in the purpose. An electromagnet is used as a magnet. An electric motor converts electricity into mechanical energy (movement), while a generator does the opposite: it converts movement into electrical energy.
Wiki User
∙ 8y agoElectrical motors and generators are machines which either convert electrical energy inputs into forces or applied kinetic energy inputs into electrical energy. In principle, any electrical generator can also be operated as a motor and vice-versa.
In a generator, mechanical energy is converted to electrical.
In a motor, electrical energy is converted to mechanical.

Why are electromagnets used in generators?
My only guess is that ,,, because electromagnets are more stronger and powerful than the ordinary magnets. Moreover they provide continuous magnetic field required for the generator. the generator in your car will have an electromagnet in the field the field will set the charge rate new cars have an alternator the field is the electromagnet in the rotor older cars have a true generator where the field is in the stator
Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
How do you turn off an electromagnet?
This is what makes a magnet an electromagnet - the ability to turn it on and off... Anyway, electromagnets can be turned off with either the help of a switch, or just by disconnecting the power supply.
Can you give me a sentence with the word generator?
A generator is a device that creates energy, or transforms it from one form into another. Here are some sentences.I bought a generator in case the electricity goes out.The generator in the dam was strong enough to power the whole city.That machine is a generator.
How does cycle pedal Generator produced electricity?
the pedals drive the wheel, the wheel drive an electrical generator.2 possibilities for the wheel to drive the generator:-the wheel does not have a tire: a belt goes in the rim and drive a puley on the shaft of the generator.-the wheel has a tire: there is a drive roller on the shaft of the generator. the drive roller is pressed on the tire.The generator can be of any kind. They are commonly car alternator or permanent magnet dc motor, but you can also drive an alternative current squirel cage generator. Depending on the chosen generator, you have to use an electric circuit appropriate for the generator.
What is generator made of?
an electromagnet
What is a generator made of?
an electromagnet
What does an electromagnet do in a generator?
in a generator electromagnets are used for producing flux for rotor to cut so it can produce current in small generator they will have residual magnetism and in big generator current is supplied to electromagnet from another small dc generator
How is the role of an electromagnet in a motor different from the role of an electromagnet in an generator?
I thinkit is different because a motor changes eletricalenergryinto motion a generator changesa motion into eletericalenergy.
Generator consisting of a coil that rotates between the poles of an electromagnet?
dynamo
Can cadmium phosphorus and cobalt with copper and zinc become a power generator in an electromagnet?
no
How are electromagnets used in the real world?
Every electric motor and generator uses an electromagnet.
What is the device that uses electromagnet induction to convert mechanical energy into electrical energy?
Generator
How electromagnets are used in real world?
Every electric motor and generator uses an electromagnet.
What describes the role of an electromagnet in a generator?
Its role is to change mechanical energy into electrical energy.
What is field winding?
The field winding on a generator is the winding that is electrified to create an electromagnet; it is generally the winding found on the rotor (the rotating part of the generator).
What best describes the role of an electromagnet in a generator?
Its role is to change mechanical energy into electrical energy.
