Do permanent magnets produce electric currents?
Permanent magnets do not produce electric currents on their own. However, when a permanent magnet moves near a closed loop of wire or coil, it can induce an electric current in the wire due to electromagnetic induction.
What are the differences between electromagnets and permanent magnets, and how do electromagnets differ from permanent magnets?
Electromagnets and permanent magnets differ in how they are created and their magnetic properties. Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets with a fixed magnetic field. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.
What is the difference between magnetic and electromagnetic fields?
Magnetic fields are created by permanent magnets or electric currents, while electromagnetic fields are created by electric currents. Electromagnetic fields are more complex and can change over time, while magnetic fields are static.
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.
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.
Do permanent magnets produce electric currents?
Permanent magnets do not produce electric currents on their own. However, when a permanent magnet moves near a closed loop of wire or coil, it can induce an electric current in the wire due to electromagnetic induction.

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.
What is the difference between magnetic and electromagnetic fields?

What do all electric motors contain?
"permanent and temporary magnets"
Do magnets affect electric?
Yes, magnets can affect electric currents and vice versa. Moving electric charges create magnetic fields, and magnetic fields can induce electric currents in conductors. This relationship is fundamental to electromagnetism and is used in many technologies, such as electric motors and generators.
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.
What part of an electric motor repelse of the permanent magnets?
The stator of an electric motor repels the permanent magnets with the help of an alternating current passing through the windings of the stator. This creates a rotating magnetic field that interacts with the permanent magnets on the rotor, causing it to turn and drive the motor.
Can magnets absorb electricity?
No, magnets do not absorb electricity. Magnets create a magnetic field that can interact with electric currents, but they do not absorb or store electricity.
What are the differences between electromagnets and permanent magnets, and how do they function differently?
Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets that retain their magnetism without an external power source. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.
