Example of Fleming’s Right-Hand Rule
Question: A conductor is moved at a velocity of 2 m/s through a magnetic field of 0.5 T directed northward. The conductor is oriented perpendicular to the magnetic field. Use Fleming’s right-hand rule to determine the direction of the induced current.
Solution:
According to Fleming’s right-hand rule:
Thumb points in the direction of the Force (F) or Motion (V)
First finger points in the direction of the Magnetic Field (B)
Second finger points in the direction of the Induced Current (I)
Given:
Velocity (V) = 2 m/s
Magnetic Field (B) = 0.5 T (northward)
Using the right-hand rule:
Point the first finger (B) northward.
Point the thumb (V) in the direction of motion (2 m/s).
The second finger (I) will then point in the direction of the induced current.
Answer: The induced current flows in the upward direction.
Fleming’s Left Hand Rule and Fleming’s Right Hand Rule
Fleming’s Left-Hand Rule and Fleming’s Right-Hand Rule are principles employed to ascertain the force’s orientation experienced by a conductor carrying electric current when exposed to a magnetic field. These rules were provided by John Ambrose Fleming and form the basics of electromagnetism. Their primary purpose is to predict the direction of the force acting on a conductor in relation to the magnetic field and the current’s flow.
