Two closed loops A and C are close to a long wire carrying a current I.

a. Find the direction (clockwise or counter- clockwise) of the current induced in each loop if I is steadily decreasing.

b. While I is decreasing, what is the direction of the net force that the wire exerts on each loop?

coil wire, increase current, put iron inside the coil

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
