PROBLEM 3:
A long, straight wire going through the origin is carrying a current of 3.00 A in
the positive z - direction. At a point a distancer = 1.20m from the origin on
the positive x - axis. Find the (a) magnitude and (b) direction of the magnetic
field.
At a point the same distance from the origin on the negative y - axis, find the
(c) magnitude and (d) direction of the magnetic field.
