Question:

Figure P28.26 shows part of the rotation of an electric motor, during which the magnetic dipole moment of the loop points to the left or has some component to the left. If the entire rotation were shown, during what fraction of the rotation would the magnetic dipole moment have some component pointing to the right?

Data from Figure P28.26
