Question

A circular copper ring, A = 0.1 m2 shown below, with 10 loops is positioned in a (Bi) 0.300 T magnetic field directed into the page. The magnetic field than disappears (Bf = 0) in 0.150 s. The loop is attached to a of 5.0 Ω resistor.

(a) What is the induced emf in the loop as the magnetic field disappears?

(b) What is the induced current in the loop?

(c) What is the direction of the induced magnetic field in the loop?

The magnetic flux through the loop shown in the accompanying figure varies with time according
to Фm 3 2.00е sin(120лt),
where
is in milliwebers. What are
the direction and magnitude of the current through the 5.00-2 resistor at (a) t = 0 ; (b)
t = 2.17 x 10-2 s, and (c) t= 3.00 s?
