Homework 30.7
In fig 30-38, the magnetic flux through the loop increases according to therelation
ΦB = 6.0 t 2 + 7.0 t,
where ΦB is in milliwebers and t is in seconds.
(a) What is the magnitude of the emf induced in the loop
when t = 2.0 s? (b) Is the direction of current through R to the right or left?
