What is rule of thumb in physics?

The right-hand thumb rule in Physics states that: to determine the direction of the magnetic force on a positive moving charge,ƒ, point the thumb of the right hand in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.

What is Fleming’s left hand rule Class 12?

Fleming’s left hand rule states that if we stretch thumb, forefinger or the index finger and the middle finger in such a way that they are mutually perpendicular to each other then the thumb gives the direction of the motion of the conductor, index finger gives the direction of the magnetic field and the middle finger …

Who is the inventor of the left and right thumb rules?

If forefinger represents the direction of the line of force, the thumb points in the direction of motion or applied force, then second finger points in the direction of the induced current”. Who Invented The Left and Right Hand Thumb Rules? The left and right hand thumb rules were founded by John Ambrose Fleming in the late 19 th century.

Why are there two hand rules in physics?

NOT ALL high school physics courses use that concept. For example, some high schools use the “left-hand” rules because it deals with ELECTRON FLOW, that is… current flow from negative to positive (the direction that electrons flow from a battery for example). The hand rules work the same but they are based on two different current concepts.
