उत्तर

According to the right-hand thumb rule, the thumb shows the direction of electric current as shown in the figure given below.

The curled fingers holding the conductor give the direction of magnetic lines.

Fleming's left-hand rule gives the direction of force experienced by a current-carrying straight conductor placed in an external magnetic field and here thumb represents force on the conductor.
