What are Factors that causes a permanent magnet generator not to generate emf?
Either the break in the circuit or loss magnetic strength of the magnet - can result into no generation
What happens when a magnet is moved towards a coil?
You will generate electricity. As the wire cuts through the magnetic field.As the magnet is moved, there will be an induced electro-motive force (EMF) which can cause a current in the coil. Once the magnet stops moving, the current will go to zero.
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 is a magnet created when electric current flows through a coil of wire?
A magnet created when electric current flows through a coil of wire is called an electromagnet.
What is used to bend electronic beams in a vacuum?
A magnet or electromagnet.
What is the definition of eletro magnet?
A magnet that becomes energised when an electric current is passed through it.
How does an alarm bell work?
magic just kidding a eletro magnet
What country invented the magnet?
No country invented the magnet. Magnets are naturally occurring objects. The Chinese were the first to use a magnet as an aid to navigation.
What did Michael Faraday discover?
He was famous for proving his theory that a changing magnetic field could generate a electric field and vice versa. this made it possible for later generations to create electric generators as well as motors
Who invented the magnet car?
Devin weetman
Who invented the credit card magnet strip?
Mike Liddy
Volts are a mesurement of what characteristic of electricity?
Volts are the measure of Eletro motive force. (EMF)
What did gregon mendel invented?
he did alot because he made magnet electricity
Who invented the first electro magnet?
William Sturgeon first invented it but, Joseph Henry invented one that could hold 1 ton!
Who is the person who invented magnets?
Nobody invented magnets because magnets and magnetic principles are found in nature. a first MAGNET was not invented, but rather were found from naturally occurring MINERALS called "MAGNETITES or "LODESTONES".
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.
When was the first magnetic disk invented and by who?
1981 by a group of scientists who found out the properties of a disc magnet
