Ans does not imply so. Thats why i asked.
Doesn't a stronger magnetic field = more magnetic lines of force
= more magnetic flux cutting?
No need to consider mgh?
Work done and G.P.E. are two different things.
Work is done when a force produces motion.
G.P.E. is the energy a body possesses due to its position
relative to the ground.
I can confuse you even more, but never mind.
The force used in WD calculation is the force used to move the
thing in the direction. Your definition seems to be wrong btw.
???
Work done = Force x Distance moved in the direction of
force.
