1 Consider a small element of the circumference of the coil, as shown in figure Al2.1, whose length is δl and which is inclined at an angle, ø, to the vertical. The Lorentz force on this element is
where δI is directed along the tangent to the circumference in the direction of i. The force’s direction is given by the right-hand corkscrew rule. When the plane of the coil makes no angle (θ = 0°) with B the angle between δ1 and B is (90° — ø) and the force’s magnitude is
