Before you can understand how electrical energy is supplied by your electric company, you need to know how it is produced. A magnet and a conductor, such as a wire, can be used to induce a current in the conductor. The key is motion. An electric current is induced in a conductor when the conductor moves through a magnetic field. Generating an electric current from the motion of a conductor through a magnetic field is called electromagnetic induction. Current that is generated in this way is called induced current. To induce a current in a conductor, either the conductor can move through the magnetic field or the magnet itself can move.

What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
What is needed for electromagnetic induction?
An electric current is produced by the change in Magnetic flux over timeRead more: How_do_electromagnets_work
What is vacuum induction melting?
Vacuum induction melting (VIM) is a metal process to use electromagnetic induction heating principle to melt the metal under vacuum conditions. In the electromagnetic induction heating process, the induction coil of induction heater will produce eddy current in order to melt the metal. This induction melting process can be used to refine high purity metals and alloys. If you want to learn more, please Visit gslipai. com or sent an email to lipaiheating@gmail.com.
Why DC cannot produce induction?
DC is uni-directional so it cant produce induction.
Who stated the law that the direction of induced current is always such as to oppose the change producing it?
This law was stated by Heinrich Friedrich Lenz (1804-1865). The law is stated as: The polarity of induced e.m.f is such that it tends to produce a current which opposes the change in magnetic flux that produces it.
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.

What is difference between induced voltage and induced current?
Just as a current flowing through a wire will produce a magnetic field, so a wire moving through a magnetic field will have a current flowing through it. This is called electromagnetic induction and the current in the wire is called induced current. A stationary wire in the presence of a changing magnetic field also has an induced current. A changing magnetic field can be produced either by moving a magnet near to the stationary wire or by using alternating current. A stationary wire in a magnetic field which is not changing will have no current induced in it. You will sometimes see this effect described as induced voltage. Strictly speaking, you will only get an induced current in the wire if it is part of a complete circuit. A wire which is unconnected at both ends will have a difference in voltage between the ends (a potential difference) but current can only flow when the wire is in a circuit. Induced current is used in electricity generation and transformers.Another AnswerThere is no such thing as an 'induced current', only an 'induced voltage'. Current will flow only if the conductor into which the voltage is induced forms part of a closed circuit.
Moving a conductor through a magnetic field a voltage is induced in the conductor is called what type of induction?
Moving a conductor through a magnetic field will produce alternatinc current (AC).

What is an e-bomb?
An electromagnetic bomb or E-bomb is a weapon designed to disable electronics with an electromagnetic pulse (EMP) that can couple with electrical/electronic systems to produce damaging current and voltage surges by electromagnetic induction. The effects are usually not noticeable beyond 10 km of the blast radius unless the device is nuclear or specifically designed to produce an electromagnetic pulse
Is flow of induce current necessary when induce emf is being produce?
There is no such thing as an 'induced current'. Voltages are induced, not currents. If a voltage is self-induced into a coil, then that voltage will oppose any change in current. If a voltage is mutually-induced into a separate coil, no current will flow unless that coil is connected to a load.
SI unit of magnetic-induction?
Electromagnetic induction is the process of inducing electric current in a coil with the help of a magnet.Whenever a conductor is moved through a magnetic field, or the magnetic field fluctuates in strength (as with an AC electromagnet), a current will be induced in that conductor. Induction cooktops work by passing a large AC current through a conductor under the cooktop, creating a fluctuating magnetic field which induces an electric current through the cookware - heating the cookware by electrical resistance.The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.CommentFurther to the original answer, it is a voltage that is induced into a conductor, NOT a current.
