An iron core and wire wound around it
The four essential parts of an electromagnet are the core (often made of iron), the coil of wire, a power source to provide electricity to the coil, and an electric current flowing through the coil.
The two ends of an electromagnet are called the north pole and the south pole. These ends are where the magnetic field lines originate and terminate, respectively.
An electromagnet is not a resistor; they are two different components in an electrical circuit. An electromagnet uses electric current to create a magnetic field, while a resistor resists the flow of electric current, which causes a voltage drop across it.
These springy pieces are called brushes. They conduct current between stationary wires and moving parts in the electromagnet, ensuring continuous contact with the commutator's contacts as it rotates.
An electromagnet operator can release metal attached to the electromagnet by turning off the electric current flowing through the electromagnet coils. This de-energizes the electromagnet, causing the magnetic field to dissipate and the metal object to fall off.
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.

I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
The comon bar magnet has two poles, and the electromagnet can be turned on and off also the electromagnet uses electricity to create a magnetic field in the first place. so the difference is normal magnet cant be turned on and off but the electromagnet can. does that answer ur question?

Yes. Usually two - called rotor and stator.
Increasing the number of coils in the wire winding around the core and increasing the current flowing through the wire are two ways to increase the strength of an electromagnet. Both of these factors contribute to creating a stronger magnetic field in the core, increasing the electromagnet's overall strength.
