(c) The teacher closed the switch and the copper rod accelerated uniformly from rest for
0.15 s.
The current in the copper rod was 1.7 A.
mass of copper rod = 4.0 g
length of copper rod in the magnetic field = 0.050 m
(2)
magnetic flux density = 0.30 T
Calculate the maximum possible velocity of the copper rod when it left the magnetic
field.
