Document Summary
2. (25 points)consider an infinitely long, hollow cylindrical wire the wire has outer radius b and the cylindrical hole at its center has radius a. A current i1 flows from left to right and the current is uniformly spread over the region between a and b. At the center of this wire is a very, very thin wire carrying a current i2 from right to left. Find the magnetic field at the point a distance c from the center such that the point is between a and b. 3. (25 points)a circular loop of wire has resistance r. it is in the horizontal plane. There is a constant vertical magnetic field of magnitude i3 pointing up. Warning: one or more words over the limit of ten means no credit! 4. (25 points)in the circuit below the capacitor is originally charged with qo on the top plate and qo on the bottom.
