Faraday-Lenz Law, also known as Faraday's Law of Induction, states that a changing magnetic field will induce an electromotive force (EMF) in a conducting loop or coil. This EMF is directly proportional to the rate of change of the magnetic field.
The Faraday-Lenz Law explains the phenomenon of self-induction, which occurs when a changing current in a coil creates a changing magnetic field that induces a voltage in the same coil. This voltage opposes the original change in current, according to the law of conservation of energy.
The Faraday-Lenz Law has many practical applications, including generators, transformers, and induction motors. It is also the underlying principle behind the operation of devices such as microphones, loudspeakers, and magnetic pickups in electric guitars.
Faraday-Lenz Law is often confused with Faraday's Law of Electromagnetic Induction. While both laws describe the relationship between a changing magnetic field and an induced EMF, Faraday-Lenz Law takes into account the direction of the induced EMF, while Faraday's Law does not.
No, the Faraday-Lenz Law is a fundamental law of physics and cannot be violated. It is based on the principle of conservation of energy and has been proven to hold true in all observed cases. Any apparent violations of the law can be attributed to errors in measurement or misunderstanding of the phenomenon.
