i, then ki = k2.The letter k will be used inwhat follows for ki and £2. Consider the ship when it is headed a degrees east of northas shown in Fig. 77. The component of H which magnetizesthe A -bar is Hcosa, and the magnetic field Ta which is pro-duced at C by the magnetization of the A -bar is k X… … Fig. 77. VTa2 + Tb2 = fcHVcos2 a + sin2 a = kH (1) Therefore the resultant of Ta and Tb is constant in value, and, * Because the magnetization of the 4-bar is proportional to H, and the fieldti is proportional to the magnetization of the A-bar.
