Please show me how did you get the answer including steps and formulas for each part

Name: Problem 9: A rectangular current loop measuring 22 cm by 31 cm is located in a region of an initially uniform magnetic field of 0.48 T, with the field pointing into the paper and perpendicular to the plane of the loop. The field is ramped down at a continuous rate to zero in 1.3 s and then ramped up again to 0.48 T at double the rate. The loop has a resistance of 6 2 d.) Find the induced emfin the loop during the ramp-down process. (10 points) a: 0.04889 v : 0.01825 v o: 0.01376 v : 0.02518 V e.) What is induced emf in the loop during the ramp-up process? (5 points) a: 0.05036 v o: 0.03667 V D: 0.02752 V a: 0.04091 V f.) Find the current during the ramp-up process. (10 points) a: 0.0052 A a: 0.0084 A D: 0.0168 A a: 0.0092A

Explanation / Answer

d)area of loop=0.22*0.31=0.0682 m²

Rate of change of magnetic field=0.48/1.3=0.37 T/s

Emf induced=0.0682*0.37=0.025 V

e)area of loop=0.0682 m²

Rate of change of magnetic field=2*0.48/1.3=0.74 T/s

Induced emf=0.0682*0.74=0.05 V

f)current during ramp up process=0.05/6=0.084 amperes

Second option is correct
