The direction of the current is indicated by the centre (middle) finger. In an electric motor, the left-hand rule is employed to denote the direction of motion. There is a relationship between the magnetic field, current, and force in both Fleming’s left and right hand rules.

If the forefinger represents the direction of the field and the second finger represents that of the current, …
WebFor what it's worth I have a textbook in my hand that reads "Lenz' law states that the direction of the voltage buildup in the coil is such that if the coil ends were short circuited, it would produce current that would cause a flux opposing the original flux change." Ref: Electric Machinery Fundamentals 3rd ed Chapman. WebJul 23, 2024 · Fleming's Left-Hand Rule. "Stretch out the forefinger, middle finger and thumb of your left-hand so that they are at right angle to one another. If the forefinger points in the direction of magnetic field, the middle finger point in the direction of current, then the thumb will point in the direction of the force".
WebUnsourced material may be challenged and removed. The various FBI mnemonics (for electric motors) show the direction of the force on a conductor carrying a current in a magnetic field as predicted by Fleming's left hand rule for motors and Faraday's law of induction . Other mnemonics exist that use a right hand rule for predicting resulting ... WebThis rule applies to motors, i.e. devices which use currents in a magnetic field to generate motion. It derives its validity from the Lorentz force, F = q v × B, in which the current goes with the charge's velocity and the induced …
