The formula for electromagnetic induction is given by Faraday's law, which states that the induced electromotive force (emf) in a closed loop is equal to the negative rate of change of magnetic flux through the loop. Mathematically, it can be expressed as emf = -dΦ/dt, where emf is the induced electromotive force, Φ is the magnetic flux, and t is time.

What is the process by which electric current is generated by placing a wire in a field?
electromagnetic induction
What is the difference between an electromagnetic rotation and electromagnetic induction?
Electromagnetic rotation refers to the physical rotation of an object due to the interaction of magnetic fields. Electromagnetic induction, on the other hand, is the process where a changing magnetic field induces an electromotive force or voltage in a conductor, causing current to flow. In summary, electromagnetic rotation involves mechanical movement, while electromagnetic induction involves the generation of an electrical current.
Who are the scientists that discovered the electromagnetic induction?
Michael Faraday is credited with discovering electromagnetic induction in 1831. He found that a changing magnetic field can induce an electric current in a circuit. This discovery laid the foundation for the development of electric generators and transformers.

What is the concept behind electromagnetic induction?
Electromagnetic induction is the process where a changing magnetic field induces an electric current in a conductor. This phenomenon is described by Faraday's law of electromagnetic induction, which states that the induced electromotive force in a circuit is directly proportional to the rate of change of the magnetic field flux through the circuit.
