A rigid conducting rod of length L = 12m is rotating about z-axis passing through
the pivot point O with the angular speed w = 3rad/s. Length Joa| is 21/3 of
the rod and length lob|is L/3 of the rod. A uniform magnetic field B = –3k (T)
is applied perpendicular to the xy-plane. Find the electromotive force ɛab
between the end points a and b of the rod.
a) Eab = 13,5V
b) Eab = 54V
c) Eab = 121,5V
d) Eab = 216,5V
e) Eab = 337,5V
