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 else can I help you with?
Is electromagnet a permanent magnet?
No, an electromagnet is not a permanent magnet. It is a magnet that produces a magnetic field when an electric current is passed through it, and the magnetic field disappears when the current is turned off.
How is a electromagnet diffrent then a permanent magnet?
An electromagnet is a temporary magnet that only produces a magnetic field when an electric current is flowing through it, while a permanent magnet retains its magnetism without needing an external electric current. Additionally, the strength of an electromagnet can be easily adjusted by changing the amount of current flowing through it, while the strength of a permanent magnet is fixed.
What is an example of a non electromagnet?
A permanent magnet, like a refrigerator magnet, is an example of a non-electromagnet. It produces a magnetic field without the need for an electric current.
How can you make an electromagnet rotate?
To make an electromagnet rotate, you can place it in the proximity of a permanent magnet. When a current flows through the electromagnet, it interacts with the magnetic field of the permanent magnet, causing the electromagnet to rotate. This setup can be used in devices like electric motors and generators.
How strong is an electromagnet compared to a permanent magnet?
An electromagnet is typically stronger than a permanent magnet because it can be adjusted by changing the electric current flowing through it. Permanent magnets have a fixed magnetic strength that cannot be easily altered.

Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
What is an example of a non electromagnet?
A permanent magnet, like a refrigerator magnet, is an example of a non-electromagnet. It produces a magnetic field without the need for an electric current.

This setup can be used in devices like electric motors and generators.
How can you find out if a magnet is permanent or not?
Look to see if it's got a coil connected to an electric power source or not. If it does, it's an electromagnet, if not, it's a permanent magnet.
Which is better a permanent magnet or an electromagnet?
electromagnet
How strong is an electromagnet compared to a permanent magnet?

Why does an electric motor use one electromagnet and one permanent magnet?
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.
How does an electromagnet's magnetic field differ from that of a permanent magnet, and does an electromagnet possess both a north and south pole?
An electromagnet's magnetic field can be turned on and off by controlling the electric current flowing through it, while a permanent magnet's field is always present. An electromagnet can have both a north and south pole, depending on the direction of the electric current.
What is the difference between a permanent magnet and an electromagnet?
A permanent magnet is made of material that naturally produces a magnetic field, while an electromagnet is created by passing an electric current through a coil of wire to generate a magnetic field.
What can you do with an electromagnet that you cannot do with a permanent magnet?
You can control the strength of an electromagnet by adjusting the current flowing through it, which is not possible with a permanent magnet. Additionally, you can turn the electromagnet on and off by controlling the electric current, allowing for greater flexibility in applications such as lifting objects or generating magnetic fields.
