An incredible amount of electrical energy passes down the funnel of a large tornado every second. Measurements taken in Oklahoma at a distance of 9.00 km from a large tornado showed an almost constant magnetic field of 1.50 10-8 T associated with the tornado. What was the average current going down the funnel? (0 = 4p 10-7 Tm/A)
a. 450 A
c. 950 A
b. 1500 A
d. 675 A
