What part of an electric motor repels the poles of the permanent magnets?
The armature of an electric motor is the part that repels the poles of the permanent magnets due to the flow of electric current through the conductors in the armature, creating a magnetic field that interacts with the magnetic field of the permanent magnets to produce motion.
How are electromagnets and permanent magnets different?
Electromagnets are temporary magnets that produce a magnetic field when an electric current flows through them, while permanent magnets retain their magnetism without the need for an external electric current. Electromagnets allow for the control of the magnetic field strength by changing the current, while permanent magnets have a fixed magnetic strength.
Why permanent magnets are needed for an electric motor?
Permanent magnets are needed in an electric motor to create a constant magnetic field that interacts with the current flowing through the motor windings, resulting in motion. The magnets help to generate torque and provide a more efficient and controlled operation of the motor compared to electromagnets. With permanent magnets, the motor requires less power input to produce the required output.
How is Law of electric charge related to electric motor?
The Law of Electric Charge states that like charges repel and opposite charges attract. In an electric motor, this law is crucial for the operation of the motor. By applying electric currents to create magnetic fields, the motor uses the interaction of opposite charges to generate force and produce motion.
How are magnets and motors related?
They both produce magnetic fields. So when together they attract.
What do magnets have to with electricity?
Faraday showed that a wire passing through a magnetic field will produce electricity. This is how a generator works. Many windings of wire on an armature spin in a magnetic field. This makes electricity.

Can magnets produce electric currents?
Motion of a coil within a magnetic field will induce a current in the coil if it can complete a circuit.

How do moving electric charges and magnets interact?
Moving electric charges produce a magnetic field, which can interact with other magnetic fields, including those produced by permanent magnets. This interaction can result in forces being exerted on the moving charges and/or the magnets, leading to phenomena such as magnetism, electromagnetic induction, and electric motors.
Do oceanic electric fields produce electric currents?
Yes
How do magnets magnetic fields electric currents and metals connect?
Magnets produce magnetic fields which can interact with electric currents to generate forces or induce currents in the conductive materials like metals. When an electric current flows through a metal conductor, a magnetic field is produced around it. This interaction forms the basis of electromagnetism and is used in various applications such as electric motors and generators.
How does the size of magnets affect electricity?
The size of a magnet does not directly affect electricity. However, larger magnets can produce stronger magnetic fields, which can impact the behavior of electric currents in nearby conductors, leading to phenomena like electromagnetic induction.
