I'm an enthusiastic physics educator with an MSc bed Net in Physics, dedicated to fostering a deep understanding of the natural world. Through interactive lectures, hands-on experiments, and thought-provoking discussions, I aim to make complex concepts accessible, while encouraging critical thinking and problem-solving skills.

Electromagnetic induction was discovered by Michael Faraday in 1831 and described mathematically by James Clerk Maxwell as Faraday's law of induction. Electromagnetic induction is a current produced by a voltage output (electromotive force) due to a changing magnetic field. This occurs when a conductor is placed in a moving magnetic field (when using an AC power source) or when a conductor is constantly moving in a static magnetic field. Through his experimentation, he found that there are certain factors that affect this voltage output. they are: Number of Coils: The induced voltage is directly proportional to the number of turns/coils of the wire. The greater the number of turns, the greater the voltage generated. Changing magnetic field: Changing magnetic field affects the induced voltage. This can be done either by rotating the magnetic field around the conductor or by rotating the conductor in the magnetic field.

Based on his experiments we now have Faraday's law which states that the amount of voltage induced in a coil is proportional to the number of turns of the coil and the rate of change of the magnetic field.
[ e = N × dΦ / dt ] Where, E is the induced voltage (in volts) N is the number of turns in the coil Φ is the magnetic flux – the amount of magnetic field at the surface (in Webers) t is time (in seconds) Visit Us: - https://irevize.com/ End
