The interplanetary magnetic field fluctuates greatly in magnitude and direction.
行星际磁场在不同的星等和方向强度差别很大。

Unlike the gravitational acceleration, the magnetic acceleration is a location-dependent variable and its magnitude and direction vary with the magnetic circuit configuration.
与重力加速度相比，磁加速度是一个依赖于空间位置的变量，其大小和方向随外磁场的磁路布置发生改变。

The magnitude and direction of this magnetic flux can be controlled in agreement with the magnitude and direction of the field current.
