The rank of the emf induced in the coil at the instants marked
Answer to Problem 1OQ
The rank of the emf induced in the coil at the instants marked
Explanation of Solution
Write the expression for induced emf by Faraday’s law.
Here,
The above equation signifies that the induced emf is directly proportional to the negative of flux that is, the induced emf will have a maximum positive value when the flux has a maximum negative value and vice versa.
