Faraday’s Law is a fundamental law of electromagnetism. This law has widespread applications in various fields including industries, electrical machines etc. some of the major ones are listed below:
=> Electrical Transformers
This is a static device which is used for increasing or decreasing thhe voltage or current. It has its applications in generating station, transmission and distribution system. The transformer works on Faraday's law.
=> Electrical Generators
The basic working principle of electrical generator is Faraday's law of mutual induction .Electric generator is used to convert mechanical energy into electrical energy.
=> Induction Cookers
The Induction cooker also works on principle of mutual induction. When current flows through the coil of copper wire placed below a cooking container, it produces a changing magnetic field. This alternating or changing magnetic field induces an emf and hence the current in the conductive container.
=> Electromagnetic Flow Meters
It is used to measure velocity of blood and certain fluids. When a magnetic field is applied to electrically insulating pipe in which conducting fluids are flowing then according to Faraday's law an electromotive force is induced in it. This induced emf is proportional to velocity of fluid flowing.
=> Musical Instruments
It is also used in musical instruments like electric guitar, electric violin etc.
