👉 Faraday's law of electromagnetic induction is a fundamental principle in physics that describes how changes in magnetic fields cause charges to move. It states that when an electric current flows through a conductor, it induces a magnetic field around the wire or object carrying the current. This magnetic field can be used to measure the strength and direction of the electric field. In essence, Faraday's law is about using electromagnetism to measure electrical currents. The key idea is that by changing the magnetic field around an object
