(c) Find the magnitude and
direction of the minimum magnetic field required to move the wire
at constant speed.
(d) What happens if the magnetic field exceeds this minimum value?
Homework Answers
(a) gravitational force
magnetic force
(b) gravitational force = magnetic force
(c) mg = BIL
=> B = mg/IL = =((.0143kg)(9.8 m/s^2))/(4.75*0.159)
B = 0.1856T
and the direction is "out of the screen'
(d) It will move with an acceleration.
