I have repeatedly run across the right hand rule of thumb but rarely have i found anything on the left hand rule of thumb. any ideas as to why this is?
The Left Hand Rule of Thumb is a basic scientific rule used to determine the direction of a magnetic field in relation to the direction of current flow in a wire. It is also known as the "Fleming's Left Hand Rule."
The Left Hand Rule of Thumb works by using the thumb, index finger, and middle finger of the left hand to represent the direction of the magnetic field, current flow, and force, respectively. When the index finger points in the direction of the magnetic field and the middle finger points in the direction of current flow, the thumb will point in the direction of the resulting force.
The Left Hand Rule of Thumb is commonly used in electrical and mechanical engineering to determine the direction of forces in motors and generators. It is also used in physics experiments involving magnetic fields and current-carrying wires.
Yes, there are some exceptions to the Left Hand Rule of Thumb. It is only applicable to current-carrying wires in a uniform magnetic field. In cases where the wire is not straight or the magnetic field is not uniform, the rule may not give accurate results.
The Left Hand Rule of Thumb was first discovered by British scientist John Ambrose Fleming in the late 19th century. He used the rule to explain the direction of forces in electric motors and generators.
