1. The problem statement, all variables and given/known data A long straight wire lies below to a circuluar loop of wire. The straight wire is carrying a constant 10A current to the right. What is the magnitude and direction of the current in the circular loop, if its diameter is 1 m and its center is 0.75m away from the wire 2. Relevant equations B = u i / 2pir B = u i N for solenoid 3. The attempt at a solution B = ui/2pir since current in wire is travelling right and the loop is above the wire, the magnetic field on the loop is going to be coming out of the screen, i'm going to assume that the magnetic field is uniform, using the distance from the center as the radius, even though.. that is probably a bad assumption? so the current will travel counterclockwise can't figure out how to find the magnitude though! should i be treating it like a solenoid, and plug in the magnetic field to get a current???
