A metal crossbar of mass m=1kg rides on a parallel pair of long
horizontal conducting rails separated by a distance L=1m and
connected to a device that supplies constant current I=1A to the
circuit. The rails are frictionless but tilted upward so that they
make an angle ?=30 with the horizontal. The magnetic field is
directed vertically downward. What minimum value of B is needed to
keep the bar from sliding down the rails? (Hint: consider the
gravity of the...

6) A vertical pair of parallel conducting rails are separated by a width of 22 cm. They are connected at the bottom by a wire that has resistance 50 m. A uniform magnetic field of strength 2800 mT points perpendicularly to the pair of rails. A 640 gram sliding conducting bar connecting the rails is released from the top and allowed to drop under the influence of gravity. Its acceleration rapidly drops to zero, and the bar continues to fall...

A straight wire carries a steady current I as shown. A metal bar
is in contact with a pair of rails and is moving upward with a
velocity of magnitude v. The direction of circulation of the
induced current in the metal bar is:- No current circulates- Left to right- Right to left

ocer long metal bar with a mass of 50-kg is falling with a constant velocity of 20 m/s towards the earth. The bar is attached to two conducting rails as shown. Ignoring air resistance and friction, determine the emf in the circuit if there is a uniform magnetic field directed perpendicular to the motion of the bar. The resistor has a value of 100.

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...
A 1.50-m-long metal bar is pulled to the right at a steady 4.0 m/s perpendicular to a uniform
A 1.50-m-long metal bar is pulled to the right at a steady 4.0 m/s perpendicular to a uniform, 0.5T magnetic field. The bar rides on parallel metal rails connected through R = 24.0Ω, as shown in the figure below, so the apparatus makes a complete circuit. You can ignore the resistance of the bar and the rails. a) (5.0 pts) Calculate the magnitude of the emf induced in the circuit. b) (5.0 pts) Find the direction of the current induced in the...

A closed circuit is formed by a solid conductor in contact with two parallel conducting rails that are closed on their left end, as shown. The solid conductor moves with a velocity of 5 m/s to the right, and the circuit resides in a uniform magnetic field of 0.80 T directed into the screen. If the rails are 0.20 m apart, what is the magnitude of the emf in this loop? X X 0.16 V 0.40 V ООО ОО 0.80...
