So to find the induced e m f, we had to first find the magnetic field using the equation they gave us A B is equal to mu, not a magnetic permeability of free space times the number of turns times the current divided by two times the radius. So I found that to be 4.19 times 10 to the minus three test love. So now we can go ahead and calculate the induced you met, which is equal to the change in flux. Delta Phi divided by the change in time Delta T Okay, well, Delta Phi is equal to the number of turns times the magnetic field times the area which is pi r squared, divided by still the change in time Delta T which we were told a 6.25 times 10 minus six seconds. Playing all those values into this expression, we find that this is equal to four 0.74 in the units Here are volts weaken box that it is the solution to our question
