Faraday’s First Law of Electromagnetic Induction
According to Faraday’s First Law of Electromagnetic Induction, “When the Magnetic Flux linked with closed-circuit changes, an EMF is induced in it which lasts only as long as the change in flux is taking place. If the circuit is closed then current also gets induced inside the circuit which is called ‘Induced current”. Changing the magnetic field changes the induced current in the circuit.
The image given below shows the deflection in the coil according to the law of Electromagnetic Induction.
Magnetic Fields Can be changed by,
- Moving a bar magnet towards or away from the coil.
- Moving the coil into the magnetic field or outside the magnetic field.
- Rotating the coil relative to the magnet.
- Changing the area of a coil placed in the magnetic field.
Faraday’s Laws of Electromagnetic Induction
Faraday’s Law of Electromagnetic Induction is the basic law of electromagnetism that is used to explain the working of various equipment that includes an electric motor, electric generator, etc. Faraday’s law was given by an English scientist Michael Faraday in 1831. According to Faraday’s Law of Electromagnetic Induction, the induced current in the circuit is directly proportional to the rate of change of Magnetic Flux.
Let’s learn about Faraday’s Law of Electromagnetic Induction, its experiment, derivation, examples, and others in detail in this article.
