1. Homework Statement [/b]
In the figure, two parallel wires carry a current I in opposite directions. A rectangular loop is midway between the wires. The current I is decreasing. The induced current through the resistor R is:
B: from b to a
C: from a to b
The Attempt at a Solution
i know that in order to find out which way the current is flowing i need to use the right hand rule, but i also need to know if the magnetic field is flowing out or going into the page? i'm not quite sure how i would approach determining that.
