Who was the first man to make electricity from magnets?
Michael Faraday was the first one who observed the production of electricity by moving magnets towards a coil of wire. This phenomenon is known as electromagnetic induction.
What are the types of electrodynamometer?
The two main types of electrodynamometer are attracted disc type and moving coil type. In the attracted disc type, two stationary coils create a magnetic field that attracts a disc attached to the moving coil. In the moving coil type, the coil is suspended between stationary magnets and experiences a force when current flows through it.
What houses magnets and coil and copper wire?
An electric motor. In a motor the coil spins within the magenetic field producing mechanical energy. In a generator the magnet spins within a coil to produce electricity. in either case the magnets can be either solid fixed magents or electromagnetic coils.
How a moving magnet and a coil of wire can be used to produced by electromagnetic induction?
Electromagnetic induction occurs when a moving magnet creates a changing magnetic field around a coil of wire. As the magnet moves relative to the coil, the varying magnetic field induces an electromotive force (EMF) in the wire, causing an electric current to flow if the circuit is closed. This principle is the basis for generating electricity in devices like generators, where mechanical energy is converted into electrical energy through the movement of magnets and coils.
How are magnets used in headphones?
Magnets in headphones are primarily used in the speaker drivers to convert electrical signals into sound. They work in conjunction with a coil of wire, known as a voice coil, which moves in response to the magnetic field created by the magnet. This movement vibrates the diaphragm, producing sound waves that we hear. The quality and strength of the magnets can significantly impact the headphones' sound quality and efficiency.
In Electromagnetic Induction would a series of magnets moving in one direction-like on a wheel- with a coil of wire on top of the wheel beside the magnets induce current and is it AC or DC?
it is dc
Who was the first man to make electricity from magnets?
Michael Faraday was the first one who observed the production of electricity by moving magnets towards a coil of wire. This phenomenon is known as electromagnetic induction.
Are magnets used to generate electricity?
Magnets can be used to generate electricity through a process called electromagnetic induction. This involves moving a magnet near a coil of wire, which induces a current flow in the wire. This principle is used in devices like generators to convert mechanical energy into electrical energy.
What is the construction and working details of moving iron and moving coil ammeters and moving coil voltmeters?
Different b/w a moving coil instrument and a moving iron instrument
What are the types of electrodynamometer?

In the attracted disc type, two stationary coils create a magnetic field that attracts a disc attached to the moving coil. In the moving coil type, the coil is suspended between stationary magnets and experiences a force when current flows through it.
Do magnets make electricity?
No. Magnets create an electric feild, not electricity.However, when you spin a magnet inside a coil of wire (or you can spin the coil of wire instead), you will create an electrical current.
Write the construction of a moving coil galvanometer?
A moving coil Galvanometer consists of a coil PQRS which is wound over a non metalic frame having soft iron core in the middle. This Coil Is suspended in b/w a powerful magnet poles N-S with the help of Phosphor Bronze wire. Concave mirror is fixed on d suspending thread upside the coil through which deflection can b noted by Lamp and Scale arrangement. The lower end of the coil is connected by hair spring.
What force makes the coilgun work?
the force of objects being attracted by magnets. the coils or solenoids act as magnets and the projectile (which must be able to attract to magnets, often iron or steel is used) is attracted to the coils. but when the projectile reaches the coil the coil must be turned off so the projectile keeps going instead of stopping at the coil.
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 a device with magnets and coils of wwire that produces electricity?
The device you are referring to is called an electric generator. It works by converting mechanical energy into electrical energy through the interaction of magnets and coils of wire. When the magnets spin within the coil of wire, it induces a flow of electrons, generating electricity.
Can magnets produce electric currents?
Motion of a coil within a magnetic field will induce a current in the coil if it can complete a circuit.
What is moving coil voltmeter?
mic or moving iron coil is instrument type works on ac and dc
