As shown in the figure, two frictionless conducting rails (#1 and #2) are attached to a 20.0 incline such that the inside edges are 80.0 cm apart. A copper bar with a mass of 0.207 kg slides (without friction) at a constant speed down the conducting rails. Sliding bar B Conducting rails B #1 #2 If there is a vertical magnetic field of 0.0506 T in magnitude in the region of the incline, determine the magnitude of the current I that flows through the sliding copper bar. I = A What is the direction of the current in the sliding bar? O from rail #1 to rail #2 from rail #2 to rail #1
