A magnet is used in the motor of an electrical fan so that the motor of the electric fan can spin and this allows you to feel the wind caused by the movement of the blades of the fan.
2 Magnets are usually used in an electrical fan.
They are placed opposite of each other with hundreds of coils of copper wire between the magnets. This set-up is known as a simple electric motor.
Detail:
Magnetic field lines pass from the north pole of the magnet to the south pole.
When an electromotive force is supplied to the coil of wire, current flows through the coil of wire.
The coil of wire produces a magnetic field that interacts with the magnetic field lines caused by the magnets.
According to Fleming's Left hand rule, the motor will rotate in a clockwise/ anti-clockwise direction due to the forces on the LHS and RHS of the coil. This creates a clockwise/anti-clockwise torque that causes the motor to rotate.
A split-ring commutator and carbon brushes are usually used.
Split-ring commutators allow the direction of current to be reversed every half a cycle of revolution to allow for a continuous rotation.
A carbon brush is used to allow for continuous electrical contact between circuit and the split-ring commutator (except when it reaches the gap).
Extra case fans are used to provide additional cooling for computers.
both sides (poles) of a magnet have the same magnetic charge
A loud speaker (like other speakers) produce sound (which is actually vibrations in the air heard by the ear) with a permanent magnet and a temporary magnet in wire form that is wrapped around the permanent magnet. (or a magnet that can be turned on and off by electricity) the speaker translates the sound into a series of electrical currents and then produces the electricity to alter the temporary magnet and making the magnets vibrate and in turn vibrates the air.
Electric current from the sound card is applied to an electromagnet changing magnetic field pushes a magnet back and forth,which is attached to the speaker cone.The moving speaker cone creates changes in the air pressure which your brain interprets as sound.
It keeps the Cpu cool, any significant heat in the Cpu can cause damage.
Not all fans do need a coil and magnet - there are hand fans, punkah walla fans belt driven fans (as in your car) and Stirling engine fans that I can think of that do not need a coil or a magnet. It is only electrically driven fans that require a coil and magnet because they work on the principles of electromagnetism.

An electrical current will flow in a conductor, when a magnet is moved next to a conductor - or when the conductor is moved next to the magnet.

No, an electric bell typically contains an electromagnet rather than a permanent magnet. When current flows through the coil of wire in the bell, it generates a magnetic field that attracts an iron striker, causing the bell to ring.
Electric fans used to fry chips can be found online from stores such as Amazon and eBay. Electric fans can also be found on most stores that sell kitchen appliances, such as WalMart in the United States.

Alnico magnets: used in sensors, speakers, and electric motors. Ceramic magnets: used in educational kits, refrigerator magnets, and crafting. Neodymium magnets: used in headphones, wind turbines, and MRI machines. Samarium Cobalt magnets: used in aerospace applications, electric vehicles, and small motors. Flexible magnets: used in signage, refrigerator decorations, and craft projects.
An electric motor uses electricity to create a magnetic field which interacts with a permanent magnet to produce motion. This motion can be harnessed to do mechanical work in devices like fans, pumps, and vehicles.
