Magnetic Field due to 3 Currents We want to find the magnetic field at one corner of a square; the field is produced by currents that are located at the other three corners of the square. (See drawing.) The square is in the

plane and the currents are flowing parallel to the

axis. We define a positive current as one flowing in the

direction. The first current, of

, is located

along the

axis, that is, at the point

. The second current, of

, is located at the far corner, that is, at the point

. The third current, of

, is located

along the

axis, that is, at the point

. Find the magnetic field at the origin. Fnter the

and

components of the field: (

Draw a careful diagram and pay attention to the r.h. rule and the direction of each current. j)
