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.
Two important parts of an electromagnet are the coil of wire, through which electric current flows, and the magnetic core, usually made of iron or another ferromagnetic material, which enhances the magnetic field strength when current passes through the coil.
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.
The mental center of an electromagnet is called the magnetic pole. It is the point on the electromagnet where the magnetic field is concentrated and strongest.
Yes, quarters can stick to a homemade electromagnet as long as the electromagnet is strong enough to attract the metal in the quarters. The strength of the electromagnet will determine how well it can attract and hold onto the quarters.
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.

Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
