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.
What else can I help you with?
What must you have for an electromagnet to work that you don't need for a regular magnet?
To make an electromagnet work, you need an electric current flowing through a coil of wire, which is not needed for a regular magnet.
What are the types of galvanometer?
The two main types of galvanometers are moving coil galvanometers and moving magnet galvanometers. Moving coil galvanometers use a coil of wire that moves in a magnetic field, while moving magnet galvanometers use a magnet that moves in a coil of wire.
How does the voltage change each time you drop the magnet through the coil?
Each time you drop the magnet through the coil, it induces a change in magnetic field, which in turn creates a voltage in the coil. This voltage fluctuates as the magnet moves through the coil, causing a change in the electrical potential.
Moving a magnet in and out of a coil of wire produces an?
electric current in the coil of wire.
When does a magnet induce an electric current in a wire coil?
A magnet induces an electric current in a wire coil when there is a relative motion between the magnet and the coil, which generates a changing magnetic field. This changing magnetic field induces an electromotive force, leading to the flow of an electric current in the wire coil.
What is the point of a magnet in a fan?
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.
Does a fan have a a magnet in it?
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.
When was Magnet's Coil created?
Magnet's Coil was created in 1995.
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.
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
What must you have for an electromagnet to work that you don't need for a regular magnet?
To make an electromagnet work, you need an electric current flowing through a coil of wire, which is not needed for a regular magnet.
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
What are the types of galvanometer?
The two main types of galvanometers are moving coil galvanometers and moving magnet galvanometers. Moving coil galvanometers use a coil of wire that moves in a magnetic field, while moving magnet galvanometers use a magnet that moves in a coil of wire.

What does the coil do in a microphone?
The coil is basically an electro magnet which is used to move the cone or diaphragm in the headphone. It works like this.... Next to the coil is a permanent magnet, when the currant from your ipod or audio device travels up the cable and into the coil it makes the coil repel the magnet and that in turn moves the diaphragm to produce the sound
