You toss a conductive open ring of diameter d=3.25 cm up in the air. The ring is flipping around a horizontal axis at a rate of 6.25 flips per second. One flip is a full rotation. At your location, the earth's magnetic field is Be=50.5 μT. What is the maximum emf induced in the ring?

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

i had this question and the answer was 3.15 miles.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
