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.
What is the maximum work that a constant magnetic field B can perform on a charge q
moving through the field with velocity v?
give full soln please!!

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
