Class 12th

Ohm's Law states that when the temperature remains constant, the current (I) flowing through a conductor is directly proportional to voltage (v), and inversely proportional to resistance (R).

As per the Faraday's Law of Induction, when a conductor is exposed to a changing magnetic field, a circulating electric current is induced, it is called the Eddy current. The Eddy currents have many applications including - non-destructive testing and induction furnaces.

The process of creating the electric current in a conductor by moving the conductor through the magnetic field or by changing the magnetic field around the conductor is known as the Electromagnetic Induction.

This scenario will also violate the principle of conservation of energy. If there is no current flowing, no force will also be required to oppose it and the whole situation just won't work as per the desire. There will be no control over the enrgy of the system.

You will be surprised to know that Lenz law is actually a result of the principle of conservation of energy. If there is no opposition to change in the magnetic flux, no external source of force will be required which will violate the principle of conservation of energy. Both these laws are interconnected to each other.

Histidine is an essential amino acid

The first and second laws weren't created together and have a gap of many years between them. Earlier, he just found out a way to calculate whether the EMF was produced or not. But with time, its direction and magnitude also needed to be calculated which resulted in him giving a second law to support his belief.

Faraday's first law only tells us if the EMF is induced or not. Unlike the second law, it doesn't have any connection with the EMF's magnitude or direction. Therefore, only the second law of faraday has a formula since it is used to calculate both the magnitude and direction of the induced EMF.
