Determination of forces and moments

The number of degrees of freedom of the system depends on both the number and location of the electromagnets and the number of households accommodated within the model. The system in Figure 7.29 can control, for example, only five degrees of freedom (the three shifts and two rotation axes of pitch and yaw) because there is only one core whose magnetization vector is characterized by a single component along the longitudinal axis of the model.

In the case of a model aircraft, the rolling moment is obtained with magnetic cores put in the wings, or building the wings with magnetic material.
