Explanation:
The area of the circular loop is given by:
The magnetic flux is given by:
is parallel to 
and is constant in magnitude and direction therefore:
Part A)
initially the flux is 
after the interval ![\Delta t= 2.4 [m/s]](https://tex.z-dn.net/?f=%5CDelta%20t%3D%202.4%20%5Bm%2Fs%5D)
the flux is
now, the EMF is defined as:
,
if we consider very small then we can re-write it as:
then:
![\epsilon =- \frac{-0.12}{0.0024} = 50 [V]](https://tex.z-dn.net/?f=%5Cepsilon%20%3D-%20%5Cfrac%7B-0.12%7D%7B0.0024%7D%20%3D%2050%20%5BV%5D)
Part B)
When looked down from above, the current flows counter clockwise, according to the right hand rule, if you place your thumb upwards (the direction of the magnetic field) and close your fingers, then the current will flow in the direction of your fingers.
