An electromagnet works by creating a magnetic field when an electric current flows through a coil of wire. This magnetic field attracts ferromagnetic materials, such as iron, causing them to be magnetized temporarily as long as the electric current is flowing.
To make an electromagnet work, you need an electric current flowing through a coil of wire, which is not needed for a regular magnet.
An electric current must flow through the coil of wire to make the electromagnet work. This current creates a magnetic field around the coil, inducing magnetism.
Yes, an electric bell uses an electromagnet to work. When the electric current flows through the coil of wire in the electromagnet, it creates a magnetic field that attracts and repels the metal armature, causing it to strike the bell and produce sound.
A toaster works using an electromagnet by converting electrical energy into magnetic energy, which connects when the toaster is turned on. The electromagnet heats up in response to the current passing through it, which then heats the metal elements inside the toaster to toast the bread slices placed in the toaster slots.
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 electromagnet makes the door close when a fire alarm goes off
A cell or other (DC) power source must, indeed, be connected to an electromagnet to make it work. It is an electromagnet. Surf the link to our friends at Wikipedia. It's a good article, and the pics are cool.
A core
it connets to the bottom of the machine

The electromagnet is a very important part of loud speakers. The electromagnet is always placed in the front of the magnet. When the electricity goes through the electromagnet the field is changed and this produces the vibrations in speakers.
The driveshaft carries the power but the whole unit does the work.

FromWhile some modern car horns are actually specialized computer audio systems, the old-fashioned electromagnetic car horns are still common. An electromagnetic horn uses an electromagnet to attract a steel diaphragm and turns that electromagnet on and off rhythmically so that the diaphragm vibrates. In fact, it uses the diaphragm's position to control the power to the electromagnet. Whenever the diaphragm is in its resting position or even farther from the electromagnet, a switch closes to deliver electric current to the electromagnet. The electromagnet then attracts the diaphragm's center. But when the diaphragm moves closer to the electromagnet, as the result of this attraction, the switch opens and current stops flowing to the electromagnet. Because of this arrangement, the diaphragm moves in and out and turns the electromagnet off and on as it does. The diaphragm's tone is determined by the natural resonances of its surface.
