What are the 4 parts of an electromagnet?
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.
What are two ends of electromagnet called?
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.
Why is an electromagnet a resistor?
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.
In an electromagnet what are the springy pieces of metal or carbon that make contact with the commutators contacts?
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.
What does an electromagnet operator do to release metal attached to the electromagnet?
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.
What do the parts of an electromagnet do?
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.
What parts do the electromagnet electric motor and speaker have in common?
A magnet

Where are the two types of electromagnet and a bar magnet commonly used?
I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
What is the difference in a common bar magnet and an electromagnet?
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?

Does an electric motor have an electromagnet?
Yes. Usually two - called rotor and stator.
Two ways to increase the strength of an electromagnet?
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.
Which is better a permanent magnet or an electromagnet?
electromagnet
In an electromagnet what are the springy pieces of metal or carbon that make contact with the commutators contacts?
