Explanation / Answer

Here,

question 1)

magnetic field , B = 0.8 T

speed , v = 43 m/s

resistance , R = 1.70 Ohm

x = 10 cm

Now , for the induced current

induced current = rate of change in magnetic flux /R

induced current = B * v * x/R

induced current = 0.8 * 43 * 0.10/1.70

induced current = 2.02 A

Now , as the magnetic flux in the loop is increasing

Using Lenz's law ,

the direction of induced current is CLOCKWISE

the correct option is 2.02 A , clockwise
