Lorentz force strength will be influenced by factors in the formula above. If a conductor in a magnetic field in amounts greater than one, then the strength of the Lorentz force will be proportional to the number of conductors. So the formula above multiplied by the number of conductors.
The coils have current in a Magnetic Field
The coil when placed in a magnetic field, then the coil will rotate.
Pictures 1132 (a) Directions terrain surrounding the conductor in the coil and (b) the magnetic field direction.
The cross-section cut from a coil depicted with two conductors with the opposite direction of the current. In Figure 1.132a shown, marked with a cross sectional top being the bottom of the home point. Terrain around the conductor as shown in Figure 1.132a. When the current carrying coil placed in a magnetic field it will be visible in the 1133 image. On the sides of the conductor will be weakening and strengthening of the field depending on the direction of the field around the conductor with the magnetic field of the magnet poles.
Image 1133 Directions motion coil in a magnetic field.
As a result, the upper conductor will move to the left and below the conductors will move to the right. This is in accordance with the rules of his left hand. When the coil has transverse 90 0 to the magnetic field, then the coil will stop moving. As shown in Figure 1.134 below.
Image 1134 Directions motion when the coil 90 0 to the magnetic field.
Torque from the coil can be calculated with the following formula:
M = torque
Lorentz force F = one conductor
r = radius of coil
d = diameter of the coil
