How was current produce or induced?
Current is induced and not produced. when an electric wire is passed through magnetic field the current is induced in the electric wire, this electric wire is enamelled copper conductor of a rotor.AnswerCurrent is never 'induced' into a conductor. It is a voltage that is induced. If that conductor is then part of a complete circuit, then the induced voltage will cause a current to flow. The induced voltage will occur even when the conductor is open circuited.
Conservative Nature of induced electric field?
The conservative nature of induced electric field is due to time varying magnetic fields. This occurs because the work done in moving a charge in a closed path in this field is not zero.
Which power source uses the rotation of giant magnets to create electricity which is then directed to the electric outlets in peoples homes?
an electric generator
Is the size of the voltage induced in a coil through which a megnet moves affected by the strength of the magnet?
Of course that has a great effect since as the magnet strength increase the number of magnetic flux lines increase increasing the induced electromotive force but motion of magnet is needed.
How does a generator use electromagnetic induction?
There is a motor in a generator which carries out this electromagnetic induction,as we switch on the generator the magnetic field lines between that motor get cuts off by the rotating coil which cause change in flux and change in flux cause induced emf,cue to emf at different points of coil cause current to get flow and then generator will get on.
Can the strength of natural magnets be increased?
The strength of natural magnets be increased in various ways. Artificial magnetism can be induced so as to increase magnetism.
What is the factors determining induced emf in dc machine?
In simple, number of turns of armature, intensity of magnet and speed of machine are major factor affecting induced emf in dc generator. If speed is increased, voltage will be increased simultaneously. Also Voltage is greater if number of turns are increased. Electro-magnet in the poles of a DC Generator also play an important role in the induced EMF. If intensity of magnet is exceeds, voltage also increased as well.
When coil turns are increased the?
Induced voltage is increased
How does hyrdro electric generate electricity?
hydro electric means electricity is produced by the using the Water(hydro). The water is made to fall forcely on the Turbine wheel it makes the turbine to rotate. Turbine is coupled to the Generator shaft. when the turbine rotates the generator rotates and emf is induced in it and the ourput is taken from it
Write any two factors on which strength of induced current depends?
The strength of induced current depends on the number of coils of the cunductor and the strength of the magnet.
How does a generator convert mechanical energy into electrical energy?
An electric generator is a device used to convert mechanical energy into electrical energy, Which is used to convert mechanical energy into electrical energy. The generator is based on the principle of "electromagnetic induction" discovered in 1831 by Michael Faraday, a British scientist. Faraday discovered that if an electric conductor, like a copper wire, is moved through a magnetic field, electric current will flow (be induced) in the conductor. So the mechanical energy of the moving wire is converted into the electric energy of the current that flows in the wire.
How is the induced voltage of separately excited dc generator affected if the speed increases?
as speed increases, induced voltage increases
Induced voltage can be increased in magnitude by?
Induced voltage can be increased by increasing flux density, velocity of conductor cutting flux lines or increasing the size of your coil.
How electricity generated in dyanamo?
A dynamo is an electric generator. The basic principle is that, when a wire (or any conductor, for that matter) moves through a magnetic field, a voltage is is induced across the wire. This will cause current to flow.
What is polar molecular alignment?
Polar orientation is defined as being the moment in which electric dipole is induced in a system such as that of an atom or molecule. This induction is completed through the use of an electric field of unit strength.
What produces electricity by spinning a magnet in a coil of wire?
A generator or alternator. If the magnetic field is permanent, the current produced from the coil will be alternating current. AC. Alternators usually work the other way round. The magnet is spun inside a coil of wire. The power is taken off from the stator. The rotor is an electromagnet, fed via slip rings on the shaft. The strength of the magnet can be varied and controlled externally, to control the output voltage.
How power plants generate electrical energy from kinetic energy?
They use a generator, which in turn uses the interactions between electric and magnetic fields. Basically, if a wire moves through a magnetic field, a voltage will be induced.
