Electromagnetic Induction (11 of 15) Lenz's Law, An Explanation

This video explains the concept of Lenz's Law. Lenz's law states that when there is a change in the magnetic flux, the polarity of the induced emf is such that it produces a current whose magnetic field opposes the change in the magnetic flux. Use the right hand rule to determine the direction of the induced current. Your fingers point in the direction of the needed induced magnetic field and your thumb points in the direction of the induced current. Electromagnetic induction is the production of an emf or voltage in a coil of wire due to a changing magnetic field through the coil. Michael Faraday is generally credited with its discovery in 1831. James Clerk Maxwell mathematically described it as Faraday's law of induction. Faraday's law states that an emf will be induced in a coil of wire when the magnetic flux through the coil of wire changes over time. Magnetic flux is calculated as the area of the coil (A) times the magnetic field strength (B). Lenz's law describes the direction of the induced magnetic field. It states that the direction of the current induced in a coil by a changing magnetic field through the coil is such that the magnetic field created by the induced current opposes the initial changing magnetic field. This is designated by the negative sign at the front of the Faraday's law equation.
