For faraday's law this video explains how a voltage and therefore a current can be induced coil of wire by changing the amount of magnetic field in the coil. This is illustrated using a simulation from Phet simulations. An emf and corresponding current are induced in the wire when the magnetic flux through the coil changes over time.

The magnetic flux is directly related to the area of the coil, the magnetic field strength, and the angle between the face of the coil and the direction of the magnetic field. The units of magnetic flux are teslas per square meter which is defied as a the Weber (Wb).
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.
