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.

How do you magnetise a needle?
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.
In which case will electric current be induced in a coil of wire?
The coil must experience a changing magnetic field in order to have a current induced. You can rotate the coil between the poles of a magnet, or rotate the magnet around the coil.
Can iron be made into a permanent magnet?
take a block of iron and then coil some wire around it, then attatch it to a power source and your iron block will act as a magnet due to the magnetic field produced by the coil. the more coils you have, the stronger the magnet and vice versa. in order to create a strong magnet you'll need to produce around 8 or 9V of electricity, so a standard 9V battery should work fine.
How can a microphone convert energy?
Most microphones sold today are "dynamic" microphones. They contain a tube (known as a coil former) with a coil of wire wrapped around it, a magnet inside the coil former, and a diaphragm glued to one end of the coil former. The diaphragm moves the coil former back and forth across the magnet; as it moves, electricity is generated in the coil.
Is a solenoid a coil of wire that has a current?
YESA solenoid is a coil of wire, which turns into a magnet when a?current?flows through

When was Magnet's Coil created?
Magnet's Coil was created in 1995.
If you had a battery running a fan and a magnet and copper coil mechanism attached to the fan generating electricity and running back to the battery Would it not run longer?
battery
How do you do a needle?
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.
How do you magnetise a needle?

What are the two ways to magnetize a magnet?
thermal - heat the magnet above the Curie Point temperature for the material it is made ofelectromagnetic - use a degaussing coil (a coil driven by AC to keep reversing the field of the magnet), slowly remove the coil from the vicinity of the magnet before turning the power off to the coil

How do you make a wind up flashlight?
You need a tube, a coil of wire, a magnet and a capacitor to store the charge.
What is the purpose of the permanent magnet in the moving coil meter?
The purpose of the permanent magnet in the moving coil meter is to measure electrical current. The coil will have a magnetic field which will react to the magnetic field of the permanent magnet. Since opposite poles attract, it will cause for the coil to move.Ê
How do wires make a fan turn?
Wires carry current to the fan from the electrical circuits of the building it is in. Inside the fan motor wires are wound in a particular fashion to make a coil. When any voltage is applied to such a wound coil, it generates an electro magnetic field. When any eletro magnet is placed near to this field, it experience a force, which is what makes the fan rotate.
