Magnetic fields generate error voltages in two circumstances: 1 if the field is changing with time, and 2 if there is relative motion between the circuit and the field.
在两种情况下磁场会产生误差电压：1磁场随时间变化。2在电路和磁场之间存在相对运动。
And the significant change in the magnetic field after the movement of the error is becoming more and more large.
而受磁后的显著变化就是机芯走时的误差变得越来越大。
