Hello students.

First of all, we have to find the magnetic flux through the loop at time t is equal to 5 .60 seconds.
00:13
So the magnetic flux through the loop is given by 5 is equal to b a cos theta where b is the magnetic field, a is the area of the loop and theta is the angle between magnetic field and normal.
00:29
So since the loop is the loop is the loop is the perpendicular so theta here is 0 and cos theta will be equals to 1 so magnetic flux since theta equals to 0 degree so 5 becomes equal to b into a now when we put the values that is 8 .00 t minus 9 .00 t square into 0 .13 we get it so value 0 .1352 t minus 0 .1521 t squared weber.

Now putting the value of time, that is 5 .60 second, we get at t is equal to 5 .60 second, we get the value of 5 .60 second, we get the value of 5 is equals to minus 4 .23 into 10 to the power minus 3 weber.

We put this value of d in above equation.

Now to find the value of induced emf, the induced emf is given by faraday's law of electromagnetic induction, that is, e is equals to minus d5i v.
