In the figure, a metal rod is forced to move with constant velocity along two parallel metal rails, connected with a strip of metal at one end. A magnetic field of magnitude B = 0.321 T points out of the page. (a) If the rails are separated by 35.4 cm and the speed of the rod is 50.8 cm/s, what is the magnitude of the emf generated in volts? (b) If the rod has a resistance of 21.7 Ω and the rails and connector have negligible resistance, what is the current in amperes in the rod? (c) At what rate is energy being transferred to thermal energy?

A 5.0 cm long, 53 grams, thin metal strip is allowed to slide along two parallel rails (that contact it at its ends). A constant 0.76 T magnetic field acts perpendicular to the two rails. If the strip is pulled with a speed of 17.8 m/s an the rails are connected to each other through a 20 omega resistor, then find the induced current in the circuit. Assume that the rod and rails have negligible resistance.

As shown in the figure below, a metal rod is pulled to the right at constant speed v, perpendicular to a uniform magnetic field directed out of the screen. The bar rides on frictionless metal rails connected through a resistor forming a complete circuit. The length of the bar between the rails is 5 cm, the magnitude of the magnetic field is 0.4 T, the resistor has a value of 10 Ω, and the speed of the bar to the...

A conducting rod is pulled horizontally with constant force F= 3.40 N along a set of rails separated by d= 0.380 m. A uniform magnetic field B= 0.600 T is directed into the page. There is no friction between the rod and the rails, and the rod moves with constant velocity v= 4.80 m/s. Using Faraday's Law, calculate the induced emf around the loop in the figure that is caused by the changing flux. Assign clockwise to be the positive...

1) 2 point charges are separated by a distance of 8 cm. The left charge is 48 mC and the right charge is -16mC. Using a full sheet of paper: draw the 2 charges separated by 8cm, centered in the sheet. (if you are missing a ruler estimate 8cm as ⅓ a paper sheet length). [6] a) Draw field lines to indicate the electric fields for this distribution. [4] b) Draw 3 equipotential surfaces, 1 each, that pass: -Through the...
