Final answer:
Electromagnetic induction is the process of creating a current by changing a magnetic field. It was discovered by Michael Faraday in 1831. This phenomenon is used in various applications including power generation and electric motors.
Step-by-step explanation:
The process of creating a current by changing a magnetic field is called electromagnetic induction. This is when a changing magnetic field induces an electric current in a conductor. The phenomenon was first discovered by Michael Faraday in 1831.
For example, when a wire is moved through a magnetic field or when the magnetic field around a coil of wire changes, an electric current is produced. This principle is used in many applications, such as power generation, transformers, and electric motors.
Another term mentioned in the question, magnelectric induction, is not a commonly used term in physics. The correct term is electromagnetic induction.
