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 theory does the moving magnet work to produce current?
Faraday's Theory of Electromagnetic Induction.
What happens if a coil is rotated between two magnets?
When a coil is rotated between two magnets, an electric current is induced in the coil due to the changing magnetic field. This phenomenon is known as electromagnetic induction. The induced current produces an electromagnetic force, creating a torque that causes the coil to rotate. This is the principle behind electric generators.
How do generators produce electricity?
Generators produce electricity through electromagnetic induction. When a coil of wire rotates within a magnetic field, it creates a flow of electrons, generating an electric current. This current can then be harnessed and used to power electrical devices.
What is called the moving a magnet inside a coil of wire will produce current?
This is called electromagnetic induction. As the magnet moves, it creates a changing magnetic field which induces a current to flow in the wire coil according to Faraday's law of electromagnetic induction.
Moving a magnet in and out of a coil of wire produces?
Moving a magnet in and out of a coil of wire induces an electric current in the wire. This phenomenon is known as electromagnetic induction and is the basis for how generators produce electricity.
During electromagnetic blank a changing magnetic field can produce an electric charge?
Electromagnetic induction is the process where a changing magnetic field induces an electric current in a conductor. This phenomenon is the basis for how generators produce electricity and is a fundamental concept in electromagnetism. It is described by Faraday's law of electromagnetic induction.
What happens when a coil is rotated between two magnets?
When a coil is rotated between two magnets, an electric current is induced in the coil due to the changing magnetic field. This phenomenon is known as electromagnetic induction and is the basic principle behind generators and electric motors. The amount of current induced depends on the speed of rotation and the strength of the magnetic field.
What happens when magnetic flux changes?
When magnetic flux changes, an electromotive force (emf) is induced in a conductor or coil according to Faraday's Law of electromagnetic induction. This induced emf can cause current to flow in a closed circuit. This phenomenon forms the basis of how generators produce electricity and how transformers work in electrical systems.
How was current produce or induced?
Current can be induced in a conductor through electromagnetic induction, where a changing magnetic field causes a flow of electric current. This can be achieved by moving a magnet near a conductor or by varying the current in one nearby. Alternatively, current can be produced by a voltage source such as a battery or generator that creates a potential difference to drive the flow of electrons.
