Define faradays law of electromagnetism

What is faradays law 

• Faraday's Law of Electromagnetic Induction is a fundamental principle of physics that states that a changing magnetic field generates an electromotive force (EMF), which is a measure of the electrical potential difference between two points in a circuit. 
• It describes the relationship between the magnetic field and the electric field and is an important concept in electrical engineering and physics. 
• The law is named after the British scientist Michael Faraday, who first discovered it in the early 19th century.
  

 Important Points to remember

• Faraday's Law of Electromagnetic Induction says a change in magnetic field creates electrical force.
• This is how electricity is generated in dynamos and transformers.
  Mathematically, it's expressed as EMF = -dΦ/dt.
  EMF stands for electromotive force.
  Φ is magnetic flux.
  t is time.
• The negative sign means the electrical force opposes the change in magnetic field.
• This is called Lenz's law.
• Lenz's law states the electrical force generated in a circuit always opposes the change in magnetic field.
• Faraday's law and Lenz's law are important for understanding electricity generation.
