A law that describes how an electric field is created by a changing magnetic field.
Electromagnetic Induction: This is the fundamental concept upon which Faraday's law is based. It refers to the production of an electromotive force (EMF) in a conductor when it is exposed to a changing magnetic field.
Magnetic Fields: This refers to the region around a magnet where its force can be felt. A magnetic field is created by the motion of electric charges.
Magnetic Flux: This refers to the amount of magnetic field passing through a given area. It is represented by the symbol Φ.
Faraday's Law of Electromagnetic Induction: This states that the EMF generated in a coil is proportional to the rate at which the magnetic flux passing through the coil changes.
Lenz's Law: This law states that the direction of the induced current in a conductor is such that it opposes the magnetic field that caused it.
Induced EMF: This is the voltage that is generated in a conductor when it is exposed to a changing magnetic field.
Self-Inductance: This is the property of a coil whereby it generates an induced EMF in response to a change in its own magnetic field.
Mutual Inductance: This is the property of two coils whereby a change in the magnetic field of one coil induces an EMF in the other coil.
Inductors: These are coils of wire that are used to store energy in an electromagnetic field.
Eddy Currents: These are currents that are induced in a conductive material when it is exposed to a changing magnetic field.
Transformers: These are devices that are used to change the voltage of an AC power supply.
Alternating Current (AC): This is an electrical current that periodically reverses direction.
Direct Current (DC): This is an electrical current that flows in only one direction.
Fleming's Right-Hand Rule: This is a rule that is used to determine the direction of the induced current in a conductor.
Maxwell's Equations: These are a set of four equations that describe the behavior of electric and magnetic fields.
Electromagnetic Waves: These are waves that are created by the interaction of electric and magnetic fields. They travel at the speed of light and include radio waves, microwaves, and light.
Faraday's law of electromagnetic induction: It states that a changing magnetic field induces an electromotive force (EMF) in a conducting circuit. This law is used in the generation of electrical power and also in transformers.
Faraday's law of electrolysis: It states that the mass of a substance produced by electrolysis is directly proportional to the amount of electricity passed through the electrolyte. This law is used in the production of metals and in electroplating processes.
