A piece of conductor strung with flat conductive plate placed diatara magnetic pole US. Observe the conductor if the conductor is energized (Figure 1128). Conductor in the above experiment will move in.

This conductor may move because their magnetic fields around each current-carrying conductor and magnetic field from pole N to S (Figure 1.129).

Conductor Motion Picture 1130 Directions
When a conductor is placed between the poles, the magnetic field around the conductor and the magnetic field from the poles to the U S, on the right side of the conductor of the magnetic field will be mutually reinforcing because it has the same direction. Being on the left side of the conductor, the magnetic field conductor with a magnetic field pole US counterclockwise so weaken each other (Figure 1.130). Therefore Conductor moves to the left.
The direction of motion can be determined by rules or left hand rule, consider Figure 1.131.

The left hand with the thumb of 90 o to the other four other fingers, placed between the poles with palms pierced by the magnetic field of the poles U. four fingers indicate the direction of the current in a conductor, then the thumb indicates the direction of motion Conductor.
Lorentz power
Flow is the movement of free electrons in matter. This resulted in the movement of cargo and pushed to the side where the force moves. It is called the Lorentz force, which amount will be greater the greater the density of the magnet, load and speed of the charge carriers.
F = Q. v. B
Lorentz force F =
Q = charge
v = velocity of charge carriers
B = density of magnetic field
