Magnetic Effects Of Current Question 370
Question: Two metal strips, each of length 2m, are clamped parallel to each other on a horizontal floor with a separation 1m between them. A wire of mass m lies on them perpendicularly as shown in figure. A vertically upward magnetic field of strength B exists in the space. The metal strips are smooth but the coefficient of friction between the wire and the floor is $ \mu $ . A current i is established when the switch S is closed at the instant $ t=0 $ . How far (in meter) away from the strips will the wire reach? (assume $ i= $ constant) $ (i=2amp.=0.2,m=1kg,B=1T) $
