The bar of length 1=20 cm, resistance 0.0005 Ohms and mass 1 kg shown in the figure slides from rest down the frictionless contacts. A magnetic field B is directed vertically upward with magnitude l Tesla. The angle is (theta)=30° a) At the instant the velocity of the bar is 0.1 m/s down the incline, find the induced current in the rod. b) Viewed-from above is the current clockwise or counter clockwise? c) After a while the bar slides with constant speed. Find the magnitude of this constant speed.
