describe the direction, use two angles: the angle from the x-axis
to the projection of the B-field on the xy-plane, and the angle
between the B-field and the xy-plane. | | ![](/sites/dl/free/0098458137/193800/ch25_ans01b.gif) (0.0K) | | ![](/sites/dl/free/0098458137/193800/POWproblem2.gif) (0.0K) | The
magnetometer is mounted on a boom away from the spacecraft in
order to isolate it from the magnetic fields generated by the
spacecraft's own electronics. | | ![](/sites/dl/free/0098458137/193800/gutter.gif) (0.0K) | ![](/sites/dl/free/0098458137/193800/gutter.gif) (0.0K) | ![](/sites/dl/free/0098458137/193800/gutter.gif) (0.0K) | ![](/sites/dl/free/0098458137/193800/gutter.gif) (0.0K) | ![](/sites/dl/free/0098458137/193800/gutter.gif) (0.0K) |
