can any body tell how to apply right hand thumb rule and fkemings left hand rule

We use the right hand rule when we want to find the direction of magnetic feild of a straight current carrying conductor.

It goes like this: point u r thumb in the direction of the current, then direction of the magnetic feild is the direction which u r curled fingers point.

Flemings left hand thumb rule gives u the direction in which the coil in a motor moves.

Here the thumb, index and middlefinger's r held mutually perpendicular to each other. Then the forefinger points direction of current, the middlefinger shows direction of magnetic feild, then the thumb shows direction of motion of the coil.

i wouldn't have given a different answer .

HEY!HAI

HOPE U HAVE SPEAKERS ON UR SYSTEM(OR) HEADPHONES

IVE GOT AN EXCELLENT DEMO FOR LEFT HAND RULE FROM YOUTUBE.
