Expert Answer

Dear student

Right Hand Thumb Rule:

                 If a current carrying conductor is imagined to be held in your right hand such that the thumb points along the direction of current, then the direction of the wrapped fingers will give the direction of magnetic field lines.

Accordingly if current in wire is vertically upward, the magnetic field lines are anticlockwise, while if current in wire is vertically downward, the magnetic field lines are clockwise.

 

 

Hope this helps.

As we know, work done by Magnetic force is always zero in moving a charged particle./So it cannot change speed of charged particle. MY doubt is that, can magnetic force change direction of motion of charged particle?
