Definition of Electromagnetic Induction

Electromagnetic induction is a phenomenon in physics where an electric current is induced in a conductor when it is exposed to a changing magnetic field. This process was first discovered by Michael Faraday in the early 19th century. The key concept behind electromagnetic induction is that a changing magnetic field can create an electric field, which in turn induces an electric current in a nearby conductor.

Electromagnetic induction can be summarized as follows:

1. When a conductor, such as a wire, is placed in a magnetic field and the magnetic field changes, an electric current is induced in the conductor. 2. The magnitude of the induced current depends on the rate of change of the magnetic field and the properties of the conductor. 3. The direction of the induced current follows Lenz's law, which states that the induced current creates a magnetic field that opposes the change in the original magnetic field.

Key Points: - Electromagnetic induction is the process of generating an electric current in a conductor by exposing it to a changing magnetic field. - The induced current is proportional to the rate of change of the magnetic field and the properties of the conductor. - Lenz's law determines the direction of the induced current, which opposes the change in the magnetic field.
