When a magnet is moved through the coil wire, it induces an electric current in the wire through electromagnetic induction. This current can be harnessed to generate electricity in devices like generators and alternators. The coil wire and magnet setup create a simple yet effective way to convert mechanical energy into electrical energy.

How can I make a motor using magnets?
To make a motor using magnets, you can create a simple design with a coil of wire and a magnet. When an electric current flows through the coil, it creates a magnetic field that interacts with the magnet, causing the coil to rotate. This rotation can be used to create mechanical motion in a motor.
Why does a fan need coil and magnet?
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 can I produce electricity from magnets at home?
To produce electricity from magnets at home, you can create a simple generator using a coil of wire and a magnet. When the magnet moves past the coil, it induces an electric current. This can be used to power small devices or charge batteries.
Where do you use magnet to generate energy?
Magnets are used in generators to convert mechanical energy into electrical energy. When a magnet moves near a coil of wire, it induces an electric current in the wire through electromagnetic induction. This current can then be harnessed as electricity for various applications.
What would happen to the voltage impulse value and the magnet is inserted in and withdrawn from the coil?
When a magnet is inserted into a coil, the magnetic field creates a voltage impulse in the coil due to electromagnetic induction. As the magnet is withdrawn, the voltage impulse will reverse in direction. This process is the basis for generating electricity in devices like generators and is used in various applications such as magnetic sensors and magnetic levitation systems.

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
Can a magnet be used to produce electricity?
A spinning magnet inside a coil of copper wire will produce electricity.
Why magnet is used for making standard resistance coil?
magnet produce emf it maintain the resistance as same
How are eltromagnets used in generators?
Any time a magnet passes through a coil of copper wire (the electro magnet) it produces electricity. In all reallity, you don't really have an electro magnet in a generator. Since the Coil or(field) is making the electricity instead of using electricity, the electro magnet isn't really a magnet; but more like an "anti-magnet" :)
can electrical currents can be used to create a magnetic field.?
Move the magnet inside a coil of wire.
What is the use of magnet in speakers?
Principle is electromagmnetism. When a conductor cuts magnetic field electricity is induced in the conductor (Fixed magnet). When a magnet is moved near a conductor electricity is generated in the conductor (Fixed conductor). In speakers magnet is fixed and the conductor (in the form of a coil is fixed to the back of the diaphragm) is allowed to move freely. As the coil is fixed to the diaphragm the movements of the coil is reciprocated by the movements of the diaphragm. Our voice induces varying current in the microphone and the same varying current is passed through the coil of the speaker hence it moves in the static magnetic field.

What are the apparatus used to show that moving magnet conduct electricity?
Volt Metre is the apparatus used to detect the electricity generated. Moving a magnet in or around coil of enamelled copper wire or vice versa will generate electricity. The electricity generated can be detected, by connecting the ends of wires of coil to a Volt Metre. The Voltage generated proportional to the speed of movement and strength of the magnet, and the number of turns of the coil.
How does an electromagnet work in a headphone?
A speaker makes sound by rapidly vibrating a paper cone or diaphragm. There is an electromagnet attached to the diaphragm. When current flows through the coil one way it becomes a magnet . Since there is a permanent magnet behind the coil, the coil is pulled toward the magnet. When the current is shut off, the diaphragm springs back to neutral. When current flows the other way, the coil pushes away from the magnet. This cycle is repeated thousands of times in a second and creates sound that corresponds to the electrical signal that it is sent. A dynamic microphone uses the same arrangement of a diaphragm attached to a coil near a magnet. The process is just the opposite. Instead of using electricity to make sound, sound is used to make an electrical signal that can be recorded. Incoming sound waves push the diaphragm in and out which drives the coil towards and away from a magnet. An electrical current is created as the coil moves through the magnet's field. This current is a signal that corresponds to the sound received by the microphone. As you can see, an electromagnetic coil is central to the operation of a speaker and a microphone. The magic of the coil is that it can act as a variable magnet, changing both in intensity and polarity. It also changes motion to electricity and electricity into motion.
