Explanation According to Faraday’s law, any change in the magnetic environment of a coil will cause an induced EMF. The induced EMF in a coil is equal to the negative rate of change of the magnetic flux times the number of turns in the coil. Given: The flux changes form − 58 Wb to 38 Wb . The time taken is 0.34 s. Formula used: The expression for the EMF is as follows: ε = − N d ϕ d t Here, d ϕ is the change in the flux, d t is the change in time, N is the number of turns. The equation is rewritten as follows: ε = − N ϕ 2 − ϕ 1 d t Here, ϕ 2 is the final flux and ϕ 1 is the flux initially. Calculation: Substitute − 58 Wb for ϕ 1 , 38 Wb for ϕ 2 , 2 for N , and 0
