Detailed explanation-1: -Electromagnetic Induction is a current produced because of voltage production (electromotive force) due to a changing magnetic field. This either happens when a conductor is placed in a moving magnetic field (when using an AC power source) or when a conductor is constantly moving in a stationary magnetic field.
Detailed explanation-2: -This process of generating current in a conductor by placing the conductor in a changing magnetic field is called induction. This is called induction because there is no physical connection between the conductor and the magnet. The current is said to be induced in the conductor by the magnetic field.
Detailed explanation-3: -Electromagnetic Induction or Induction is a process in which a conductor is put in a particular position and magnetic field keeps varying or magnetic field is stationary and a conductor is moving. This produces a Voltage or EMF (Electromotive Force) across the electrical conductor.
Detailed explanation-4: -Electromagnetic induction is the creation of an electro-motive force (EMF) by way of a moving magnetic field around an electric conductor and, conversely, the creation of current by moving an electric conductor through a static magnetic field.
Detailed explanation-5: -Electromagnetism refers to creating a magnetic force using an electric current. Electromagnetic induction uses changes in a magnetic field to run voltage through a conductor.
