What parts do the electromagnet electric motor and speaker have in common?
A magnet
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 parts of an electromagnet?
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.
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?
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 is a magnet made by electric current?
An electromagnet.

Why electromagnet is different from a permanent magnet because an electromagnet what?
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.
Who built the first electromagnet?
Linc Robinson built the first electromagnet.
