Question

10. (15 pts.) he loop below is in a magnetic field of magnitude 5.0 T, directed into the page. X X a. When the radius of the loop is 15 mm, what is the mux X X X through the loop? (5 pts X X XX X X X X b. If the radius increases from 15 mm to 27 mm in 5.2 s, what is the induced emf? (5 pts.) A t c. What direction is the induced current in the loop? (5 pts.) t2 l I. (10 pts.) Two parallel wires of length 1.2 m, separated by 2.5 mm, are carrying the same current I, but in opposite directions. a. If the force between the wires is 27 LN, what is the current in either wire? (5 pts.) T. R g both versions of the Right-Hand Rule, are the wires attracted or repelled? (5 pts.)

Explanation / Answer

Force between two wires= 2 x 10^-7 x Ix I x length of wire/d where I is the current in each wire and d is the separation

so, 27 x 10^-6 = 2 x 10^-7 x I^2 x 1.2/2.5 x 10^-3

so, I= 0.53 A

b. opposite currents repel each other
