Answer:
i = 0.5 A
Explanation:
As we know that magnetic flux is given as

here we know that
N = number of turns
B = magnetic field
A = area of the loop
now we know that rate of change in magnetic flux will induce EMF in the coil
so we have

now plug in all values to find induced EMF


now by ohm's law we have
