A conducting rod of mass m and resistance R, slides with no
friction on an horizontal rail of width l and negligible
resistance. At t=0, the rod passes O with a velocity v0. The rail
is closed from one side only, so that the rod actually forms a
closed circuit. A constant magnetic field B is present everywhere,
perpendicular to the plane of the rail. v0, m , l, R and B are
given?

A square rod has a resistance R and slides without friction down parallel conduction rails of negligible resistance, as shown in the figure. The rails are connected at the bottom so that the square rod and the rails form a conducting loop. The rails are inclined at an angle 0 = 45° to the surface. A uniform magnetic field B exists throughout the region along the Z-direction. The length of the square rod is L. For the coordinate system given...

A conducting rod of length 4.5 m is sliding downward between two vertical rails without friction. The rails have negligible resistance, but the resistance of the rod is 0.8 Ω. The rails are connected to an 23.3-Ω resistor, and the entire apparatus is placed in a 0.1-T uniform magnetic field. The rod is sliding down at the constant velocity of 7.4 m/s. What is the value of the constant current generated in the rod?
