You are looking down on a N = 17 turn coil in a magnetic field B = 0.5 T which points directly down into the screen. If the diameter of the coil d = 3.8 cm, and the field goes to zero in t = 0.24 seconds, what would be the magnitude of the voltage (in Volts) and direction of the induced current? Indicate the direction of the current by the sign in front of your voltage: counterclockwise is positive, clockwise is negative.

Complete Question

The diagram for this question is shown on the first uploaded image

The  voltage is

The  direction of the induced current is clockwise

Explanation:

From the question we are told that

   The number of turns is  N  = 17

     The  magnetic field is  

     The diameter is  

      The  time interval is

The induce emf is mathematically represented as

Here is the magnetic field experienced by the coil before entering the magnetic field given in the question  i.e  

Here the negative sign show that the induced voltage is moving in a direction opposite to the change magnetic flux

  The  area is mathematically represented as

=>  

=>  

Hence

The  direction of the induced current is the same as that of induced voltage

    Thus the direction is clockwise

the answer is a 3.8cm
