2.3.2. Force action on current-carrying coils (motor principle)
As opposed to Figure 17, Figure 19 features a conductor loop is positioned in a rotatable manner. A force is exerted on both conductor sides. This yields an overall torque.
M = 2 • F • r
1 Radius, 2 Effective length, 3 Current direction, 4 Force action
The following equation is forthcoming from the electrodynamic law of force
M = 2 • B • l • I • N • r
M = c • Φ • I
