This …WebFaraday discovered that if the magnetic field through a loop of wire varies in time then an emf is induced around the loop. Faraday was able to observe this effect because the emf gives rise to a current circulating in the loop. Faraday found that the magnitude of the emf is directly proportional to the time rate of change of the magnetic field.

The statement of the law is: The polarity of induced emf is such that it tends to produce a current which opposes the change in magnetic flux that produced it.raksilan prisma aukioloajatWebThe magnitude of the magnetic field and area of the loop are fixed over time, which makes the integration simplify quickly.
