Use of magnet: Fridge doors

How it works: There are unlike poles of the magnet on the fridge and fridge door to ensure that the fridge door can be attracted to the fridge to close tightly.

Use of magnet: Vacuum cleaner



How it works:Your vacuum cleaner has an electric motor that runs by magnetism. Inside the motor, wire coils produce repelling forces when electric current flows through them. The forces make the motor spin. Unlike refrigerator magnets, which use no power, the magnetic coils in the motor have no magnetism when the vacuum cleaner is turned off. The coils have much stronger magnetism than the magnets you stick on your refrigerator door.

Use of magnet: Magnetic Knife Rack

How it works: 
Kitchen knives are usually made of 400 series of stainless steel. Stainless steel 400 series generally contain chromium, which is remarkable for its magnetic properties. Magnetic field in kitchen knives and knife rack allows these two objects to stick to each other. By hanging the knives on the wall, it is easier for people to reach for it when there is a need.

Electromagnet

How it works:
The electromagnet is located at the end of the crane and can be switched on or off. When it is switched on, the magnet attracts iron and steel from a pile of mixed rubbish . The magnet can be switched off to drop the metal attracted, in another place.

Use of magnet: Audio speaker


How it works: In order to translate an electrical signal into an audible  speakers contain an electromagnet: a metal coil which creates a magnetic field when an electric current flows through it. ... This means that it is in turn attracted to and repelled from the permanent magnet, vibrating back and forth.

Use of magnet:
The dark magnetic strip on the backside of a credit card stores data in much the same way as a computer’s hard drive does.

How it works:
A stripe of magnetic information that is affixed to the back of a plastic credit or debit card. It can be black, brown or silver in color. Often, it's called a "magnetic swipe" card, because the card is activated by swiping it through a device that can read the data in the stripe. The credit card's magnetic stripe contains three tracks of data. Each track is about one-tenth of an inch wide. The first and second tracks in the magnetic stripe are encoded with information about the cardholder's account, such as their credit card number, full name, the card's expiration date and the country code. Additional information can be stored in the third track. (Info extracted from https://www.creditcards.com/glossary/term-magnetic-stripe.ph)

The hardware of most doorbells consist of a metal bell and metal clapper that, when the magnetic charges causes them to clang together, you hear the chime inside and you can answer the door. The bell rings, the guest releases the button, the circuit opens and the doorbell stops its infernal ringing. This on-demand magnetism is what makes the electromagnet so useful.

Use of magnet : Compass helps people find their way  when they are lost. For example when they are lost in the forest, hiking or on a trip to a new location.

How it works : its needle aligns itself and points toward the top of Earth's magnetic field, giving explorers a consistent sense of direction. The north end of a compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic North Pole attracts the "north" ends of other magnets, it is technically the "South Pole" of our planet's magnetic field.

Use of magnet: Produce sound / music.

How it works: The speaker consists of a stationary magnet in a metal frame, a paper cone and a wire coil attached to the cone’s center. When an electric signal flows through the coil, magnetic forces between the coil and the magnet make the cone vibrate in and out. The vibration produces the music you hear.

Maglev is a system of train transportation that uses two sets of magnets, one set to repel and push the train up off the track as in levitation then another set to move the 'floating train' ahead at great speed taking advantage of the lack of friction. Within certain "medium range" locations.  Maglev can compete favorably with high speed rail and airplanes.
With Maglev technology, there are no moving parts. The train travels along a guideway of magnets which control the train's stability and speed. Maglev trains are therefore quieter and smoother than conventional trains, and have the potential for much higher speeds and thus is able to accelerated and decelerate much faster than conventional trains.

Use of magnet : Magnetic catches are a simple and effective way to hold doors in cabinets and enclosures closed and have no moving parts. 

How it works: The catch consists of a magnet or series of magnets within a casing which is fixed to the cabinet door. When the door is closed, in the case of metallic cabinet, it is held closed by the magnet. If the cabinet is non-metallic a magnetically receptive counter plate can be fitted to the unit. When the door closes the magnetic catch and the counter plate meet and are held together magnetically securing the door. Magnetic latches are available with a wide range of holding forces and can also tolerate misalignment
