ectrical ap-paratus, cylindiical coils of wire of one or more layers are employed,and it is of interest to examine the magnetic properties of such a coilwhen a current is sent tliiough the wire. We shall investigate thestrength of the field at points on the axis, assuming that the radius ofthe wire… … 266*] CYLINDRICAL COIL 363 to the axis. For each turn of the spiral, the projection parallel to theaxis is a straight line equal to the pitch of the spiral, and the pro-jection perpendicular to the axis is a circle of the same radius asthe cylinder. If the section of the cylinder is small, the…
