An electromagnet produces a magnetic field when current is passed through it wire winding.

We produce electric field and magnetic field. If we change the electric field with time (so magnetic field alse change), required frequency, then we produce electromagnetic wave.
A magnetic field is generated whenever a current is passing through a wire.
An electromagnet produces a magnetic field because when an electric current flows through a coil of wire, it creates a magnetic field around the wire. This magnetic field is stronger when the current is stronger and when the coil has more turns.
It doesn produce electricity. It uses electricity and shows magnetic properties.
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.
An electromagnet requires only two parts, a core of ferro-magnetic material and wires winding around it. The wires magnetize the core when current flows through them, and the core then creates the magnetic field which the electromagnet is intended to produce.
When you turn off an electromagnet, the magnetic field it was producing disappears and the magnetism is lost. This is because an electromagnet relies on the flow of electric current to produce the magnetic field, and when the current is turned off, the magnetism is no longer sustained.
Increasing the number of loops in an electromagnet strengthens the magnetic field produced, resulting in a stronger electromagnet. Conversely, decreasing the number of loops weakens the magnetic field, making the electromagnet less strong.
No, an electromagnet generates a magnetic field when an electric current passes through it but it does not produce electric energy on its own. Electric energy is typically produced by generators that convert mechanical energy into electrical energy through electromagnetic induction.
In speakers, an electromagnet works by receiving an electric current which creates a magnetic field. This magnetic field interacts with the permanent magnet in the speaker, causing it to vibrate. These vibrations produce sound waves that are then amplified and emitted through the speaker cone.
The electromagnet in an electric motor is called the rotor. It is typically made up of one or more coils of wire that interact with the stator's magnetic field to produce rotational motion.
