Magnets are used to make electric motors and generators. Without these electric motors and generators we would not have telephones, lights, electric heat, television, or computers.
Some items that use electromagnets are: Maglev trains, car crushers, scrap metal sorters, telephones, computers, doorbells, tape recorders etc
Maglev trains use super conducting magnets in the track and on the underside of the train to “float” above the track. Maglev trains use magnetic repulsion. Maglev trains can travel very fast, up to 480 km/h (300 mph). These Maglev trains are being used in Japan. This train line opened in April 1997. In April of 1999 this train was clocked at an incredible 343 miles an hour! The United States government has set aside 1 billion dollars to build a Maglev train.
Sometimes magnets are used to sort magnetic and non-magnetic materials. Examples of magnets being used as separators are:
Metals separated from ore
Food manufactures us magnets to keep small metal filings from machinery from getting into food.
Candy and coke venders use magnets to separate coins from slugs that are put into their machines.
At home we use magnets to hold things up or to pick up small things:
sewing pins
electric can openers
Magnets can hold things to the refrigerator.
Magnets are also used in compasses to show attraction and repulsion. Magnetized compasses are used to detect underground metal pipes.

Pretty sure you're not using "the" properly, as it is not clear what "magnets" you're referring to.
Anyhows, I'll just assume that you'd like to know "where magnets are used":
1. in the rubber seals of the doors of a fridge to keep it closed
2. in many microphones
3. in many speakers
4. in dc motors
5. in many generators
6. in compasses
7. in those things that claim to alleviate pain through the use of magnets
8. in hard drives

Mostly magnets are use in speakers and toys. also refrigerators, doors, compasses, hand bags, generators, cranes, scrap werehouses, automobile industries,radors,some switches etc...

On my fridge to hold all my pictures my daughter has either colored or drawed. Or to hold up their 100% they got on a test.
