Flemings Right Hand Rule
Solution
Fleming's Right Hand Rule is a simple rule to remember the direction of three mutually perpendicular vectors in physics. It is used in electromagnetism to predict the direction of motion in motors, the direction of magnetic field, and the direction of current.
Here are the steps to apply Fleming's Right Hand Rule:
-
Stretch out your right hand with the thumb, forefinger and middle finger at right angles to each other.
-
If the forefinger represents the direction of the magnetic field (from North to South), the thumb represents the direction of motion or applied force, then the middle finger will represent the direction of the induced current (from positive to negative).
-
This rule is applicable for generators where mechanical energy is converted into electrical energy.
Remember, this rule is different from Fleming's Left Hand Rule, which is used for motors where electrical energy is converted into mechanical energy.
