bcoz the magnetic force acquired on the charge is always perpendicualr to the velocity of the charge, so the field can never do any work on the charge.

W=0
because, the force on the charge is always perpendicular to the force applied by the magnetic field on the charged particle....

oh god!! does that mean a moving charge's kinetic energy cannot be affected by a magnetic field?

right subhomoy~~ATGS

always KE is never affetced by Magnetic Field

does that mean only direction of velocity of a moving charge is affected by magnetic field!!

that means ki the speed remains constant??

WOW!![1][1]

ya speed always remains unchanged in magnetic firld
and direction may or may not change
