You are trying to design a motor for a hair dryer manufacturer. For the motor to work properly, a wire must be deflected upward. Which of the following principles could be used to produce this motor effect?
A. Moving charges experience a force that is perpendicular to both their motion and the electric field they traverse.
B. Moving charges experience a force that is parallel to both their motion and the electric field they traverse.
C. Moving charges experience a force that is perpendicular to both their motion and the magnetic field they traverse.
