==Calculating the Size and Direction of the Force==
The size of the force is given by <math>F<sub>electromotive</sub> = qvB(sinX)</math> where q = charge on the particle (coulombs), v = velocity of the particle (ms<sup>-1</sup>), B = magnetic field density (tesla) and X = angle between field and direction of the charge (only the vector component of the particle perpendicular to the field will produce the force).
The size of the force is given by ''F<sub>electromotive</sub> = qvB(sinX)'' where q = charge on the particle (coulombs), v = velocity of the particle (ms<sup>-1</sup>), B = magnetic field density (tesla) and X = angle between field and direction of the charge (only the vector component of the particle perpendicular to the field will produce the force).
The direction of the force on a positively charged particle can be easily obtained using the right hand push rule (this avoids mapping the interaction between the fields). The right hand is held with the palm pointing away from the body as if pushing the air, the fingers point to the sky and the thumb points to the left (ie at a right angle to the fingers). The direction of the magnetic field is represented by the fingers, the velocity of the particle is represented by the thumb and the force of deflection on the particle is the direction the palm is facing (ie away from the body). This setup can then be orientated to suit any situation. If the charged particle is negatively charged the left hand can be used.
