A flat loop of wire consisting of a single turn of cross-sectional area 7.10 cm2 is perpendicular to a magnetic field that increases uniformly in magnitude from 0.500 T to 2.10 T in 1.07 s. What is the resulting induced current if the loop has a resistance of 1.60?

The induced current is  

Explanation:

From the question we are told that

   The area is  

   The initial  magnetic field is  

    The magnetic field after t =1.07 s is  

     The resistance of the loop is

Generally the electromagnetic field induced is mathematically represented as

Where N is the number of turns which is 1 in the case of this question since there is only one loop

 So

=>  

Generally the value of the current is mathematically represented as
