resultant field.This has the value VSTTWiand is inclined to the direction ofOHj by an angle <^ whose tangent is g:-, that is, tan 4> = s^ Both H±±1 ^ ±±1 and cJ3, which define the resultant field, vary periodically ; for when t = 0, then Ho = 0, and H = oHj sin d. Also when t = , H*! = 0, and… … and, tan (f) = sin jyt
