Induced EMF , E = -dφ/dt
 
where φ is flux of magnetic field
 
Induced Current , E/R = - (1/R) ( dφ/dt ) 
 
where R is resistance of coil .
 
At time t = 0 to t = 2 s, induced Current = -(1/50) × [ (25)/2 ] = -0.25 A 
 
At time t = 2 to t = 4 s, induced Current = 0 , because flux is constant
 
At time t = 4 to t = 6 s, induced Current = - (1/50) × [ ( -20 -25 ) / 2 ] = 0.45 A
 
Magnetic flux and induced current are plotted in figure as  function of time
