Some doorbells have a "clapper" (a small hammer) that hits one or more bells (often tubes of metal) the action of the hitting can be initiated by an electromagnet pulling the clapper. The doorbell switch can in such an arrangement close the circuit to the electromagnet.

What are electromagets in?
Electromagnets are found in things like doorbells,telepones,radios, VCR's,DVD players,computers/laptops,tape decsk,generators,and sound speakers.
How are electromagnets used in real life?
Electromagnets are used to lift large masses of magnetic materials, such as scrap iron. They are essential to the design of the electric generator and electric motor and are also employed in doorbells, circuit breakers, television receivers, loudspeakers, atomic particle accelerators, and electromagnetic brakes and clutches. Electromagnetic propulsion systems can provide motive power for spacecraft.
How do electromagnetic devices impact on society?
Electromagnets are widely used in the society. An advantage is that humans use electromagnets in all kinds of useful utensils like doorbells, telephones, cranes, computer disks, mobile phones, televisions and so on. Also eye surgeons, while performing operations, use electromagnetic devices to recover the patient.

The electromagnets that are used in junkyards are called just that, electromagnets. They are used to sort out different types of metals.
Where are electromagnets currently found?
In the real world? Everywhere... Doorbells, hard-drives, electric motors, coil-guns, tape players (if you can remember those), cellphones, speakers, electric guitars,
Where use electromagnets?
Inside of electric motors are electromagnets and permanent magnets. In a metal junk yard large electromagnets are used to pick up metal. In MRI's large electromagnets are used for imaging.
What are doorbells typically made from?
A doorbell consists of a solenoid and a piston. These can be made from a variety of plastics and/or conductive metals. Brass is a common example used in doorbells.
