How would I go about part A to solve for B and C?
10. + A square loop of
wire of side 2.3 cm
and electrical resis-
2.3 cm
tance 79 2 is near a
2.3 cm
long straight wire
that carries a cur-
-9.0 cm-
rent of 6.8 A in the
direction indicated. The long wire and loop both lie in
the plane of the page. The left side of the loop is 9.0 cm
from the wire. (a) If the loop is at rest, what is the
induced emf in the loop? What are the magnitude and
direction of the induced current in the loop? What are
the magnitude and direction of the magnetic force on the
loop? (b) Repeat if the loop is moving to the right at a
constant speed of 45 cm/s. (c) In (b), find the electric
power dissipated in the loop and show that it is equal to
al the rate at which an external force, pulling the loop to
keep its speed constant, does work.
