A metal bar is in contact with a pair of metal parallel rails as shown. A steady uniform magnetic field B, perpendicular to the plane of the rails and pointing outward from the page, is present. The bar is in downward motion with velocity of magnitude ?. The direction of the induced current through the resistor R is
Homework Answers
E = I/R = BLVsin[theta]
by fleming right hand rule
index finger = field
thumb direction of velocity
middle finger induced current or voltage
so direction is down the rail from rod 1 to rod 2[1 is above 2]

A pair of conducting, parallel, frictionless rails is mounted on an insulating platform. The distance between the rails is L = 0.20 m. The rails are connected on one end by a R = 10.12 resistor. A conducting bar of mass 1.2 kg can slide on the rails without friction. When the conducting bar is at x = 0, the enclosed area of the loop is 0.03 m2. There is zero resistance in the conducting bar or rails. A uniform...

A metal bar of mass 500 g slides outward at a constant speed of 1.5 cm/s over two parallel rails separated by a distance of 30 cm which are part of a U-shaped conductor. There is a uniform magnetic field of magnitude 2 T pointing out of the page over the entire area. The railings and metal bar have an equivalent resistance of 150Ω.150Ω. (a) Determine the induced current, both magnitude and direction. (b) Find the direction of the induced...
