An electric motor typically uses one electromagnet and one permanent magnet to create a magnetic field that interacts to produce motion. The electromagnet's field can be easily controlled by varying the electric current, allowing the motor's speed and direction to be changed. The permanent magnet provides a fixed magnetic field that interacts with the variable field of the electromagnet to generate the rotational force needed for the motor to work.

Which TWO types of magnets do you need to make a simple motor?
The most basic of electric motors consists of a permanent magnet and an electromagnet. This is not a requirement for all types of electric motors and most modern electric motors do not have permanent magnets. The stator and rotor are the two active elements of a simple electric motor and both have magnetic fields in the various types and designs of simple motors.
How does an electric motor rotate once it's electromagnet is aligned along the magnet field or it's permanent magnet?
Once the electromagnet in an electric motor is aligned along the magnetic field produced by permanent magnets, a torque is generated due to the interaction of magnetic fields. This torque causes the rotor (part of the motor that holds the electromagnet) to rotate. The rotation continues as the electromagnet switches polarity to stay aligned with the changing magnetic fields, creating a continuous rotation.
What is the advantage of using an electromagnet in an electric motor than a permanent magnet?
An advantage of using an electromagnet in an electric motor is that its magnetic field can be easily controlled by adjusting the current flowing through the coil, allowing for variable speed and torque control. This makes electromagnets more versatile compared to fixed-strength permanent magnets in electric motors.
What device uses an electromagnet to change electrical energy to kinetic energy?
An electric motor uses an electromagnet to convert electrical energy into kinetic energy. The electromagnet creates a magnetic field that interacts with a permanent magnet, causing the motor to spin and generate mechanical motion.
Advantage of using electromagnet in an electric motor rather than a permanent magnet?
convert electrical energy to energy of motion...! the usage of an electromagnet allows us to control the flow of electrons to the electric rotor,thereby allowing us to control the working of the rotor,whereas with a permanent magnet there will be a continuous supply of energy which can be stopped only if the magnet is damaged or heated.

An electric motor uses an electromagnet to change?
An electric motor uses an electromagnet to create a magnetic field, which interacts with a permanent magnet to generate rotational motion. When an electric current flows through the electromagnet, it creates a magnetic force that causes the motor to turn.

How is electricity transformed into motion?
A motor transforms electricity. Inside the motor, there is a permanent magnet and an electromagnet, which can rotate. When the circuit is closed, the electromagnet is constantly repelled and attracted to the permanent magnet. This will cause the electromagnet to turn. It also causes anything that is attached to the electromagnet to turn, causing motion.
What part of an electric motor repels the poles of the permanent magnet?
commutator
Why is a permanent magnet necessary for an electric motor to function effectively?
A permanent magnet is necessary for an electric motor to function effectively because it creates a magnetic field that interacts with the electric current flowing through the motor's coils, causing the motor to generate rotational motion. This interaction between the magnetic field of the permanent magnet and the electric current is essential for the motor to convert electrical energy into mechanical energy efficiently.
How Electric Motors Work?
Many people are not aware of the fact that electric motors exist all around them. They are used in their car, washing machine, food processor, and so on. Even fewer people are aware of the way in which an electric motor actually works. Here are some of the basics. An electric motor is powered by the forces of electricity and magnetism. Magnets are used in order to create motion. Consider a simple magnet, with a north and south pole. The fact that a pole is attracted by its opposite and repulsed by the same is utilized in order to create the motion inside of an electric motor. The heart of the electric motor is the rotor, which is an electromagnet. An electromagnet consists of copper wiring that has been wound in a circle. When electricity moves in a circle, it creates a magnetic field. When electricity moves through the coil of wire, it becomes a magnet. When electricity is not passing through it, it is simply a coil of copper wiring. Inside an electric motor, there is at least one permanent magnet. When the electromagnet is activated, the north pole of the permanent magnet faces the north pole of the electromagnet. The permanent magnet is attached to an arm that can rotate around the electromagnet. Since the permanent magnet is repulsed by the north end of the electromagnet, it swings around to the other side. The direction of the electricity through the electromagnet is then reversed. This causes the north end of the electromagnet to become the south end. When this happens, the permanent magnet against swings over to the other side. This is the basic principle behind how all electric motors work. There are two basic types of electric motors: those that run on alternating current and those that run on direct current. A motor that runs on alternating current can take advantage of the fact that the direction of the electricity is constantly reversing in order to constantly reverse the polarity of the electromagnet and keep the electric motor running. In the case of direct current, a device known as a commutator is used in order to switch the direction of the current back and forth.
What makes electrical energy change into energy of motion?
Electrical energy can be converted into motion energy by using an electric motor. When electric current flows through the coils of the motor, it creates a magnetic field that interacts with a permanent magnet or electromagnet to generate a rotational force, causing the motor to turn and producing mechanical motion.
