Question

state right hand thumb rule ?

pls answer ​

Answer 1

Right hand thumb rule states that, “If you imagine holding a current carrying wire in your right-hand with your thumb pointing towards the direction of electric current flow then the direction in which your fingers curl, gives the direction of lines of force of the magnetic field”.

Answer 2

If we hold the current carrying conductor in the right hand such that the thumb points in the direction of the magnetic field lines, then the fingers encircle the wire in the direction of the electric current.
