Consider the motional emf arrangement shown in the figure. The 27.5 cm long rod moves at a constant 6.50 m/s. What is the strength of the magnetic field, in Teslas, if a 48.0 V emf is induced? BLANK-1 What is the magnitude of the current, in Amperes, that flows through the 75.0-ohm load resistor? BLANK-2 What force, in Newtons, must be applied to the rod to maintain its constant speed?

The conducting rod shown in the accompanying figure moves along parallel metal rails that are 25-cm apart.
The conducting rod shown in the accompanying figure moves along parallel metal rails that are 25-cm apart. The system is in a uniform magnetic field of strength 0.75 T, which is directed into the page. The resistances of the rod and the rails are negligible, but the section PQ has a resistance of 0.25 Ω. (a) What is the emf induced in the rod when it is moving to the right with a speed of 5.0 m/s? (b) What force is required to...

1. A rod (length = 10 cm) moves on two horizontal frictionless conducting rails, as shown below. The magnetic field in the region is directed perpendicularly to the plane of the rails and is uniform and constant. If a constant force of 0.60 N moves the bar at a constant velocity of 2.0 m/s, show that the current through the 12-2 load resistor is 0.32 A. 1222 An ideal step-down transformer has 200 primary turns and 50 secondary turns.
