A metal crossbar with resistance R lies across conducting rails in a constant magnetic field B pointing out of the page as shown. The bar is moving at a speed v as indicated to the right. The rails have negligible electrical resistance compared to the crossbar, and you may neglect friction in the sliding of the crossbar. (a) What is the direction of the induced current flowing in the crossbar? Explain your reasoning. (b) Systematically develop an expression for the...
The apparatus below is submerged in a uniform, constant magnetic field
The apparatus below is submerged in a uniform, constant magnetic field, B. A conducting bar moves to the left at a constant speed v on two conducting rails joined as shown. As a result of the bar moving through this constant magnetic field, a current I is induced in the indicated direction. Which one of the following directions is that of B? a) Toward the right b) Toward the left c) Parallel to the long axis of the bar d) Into...

The picture below is inside of a uniform and constant magnetic field of 2 nt. The magnetic field is directed into the page. A conducting rod slides (length = 10 cm) moves on two parallel frictionless conducting rails. What is the energy absorbed in one hour by the 12-ohm resistor if the bar moves to the right at a constant velocity of 1.75 m/s?

23. As shown in the figure below, a conducting bar of length - 20 em is pulled to the left on frictionlessrails at a constant speed of y 20 m/s. A uniform magnetic field directed out of the page has a magnitude of B-O1T If the rails are connected to a resistor of resistance R-4.0 Ω andan ideal battery of emf e-1.6V, find the magnitude and direction of the current flowing in the circuit formed. Assume that the bar and...

In a region with a constant magnetic field as shown, there are
two conducting frictionless horizontal rails, a resistor and some
conducting wire along the left side and a conducting bar on the
right side that is free to slide left or right. The bar is
initially at rest but at time zero a force is applied to the bar
pulling it to the right so that the distance s increases with
time.

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...

1) In a region of space with an external magnetic field of 0.55-T in the vertical direction, two metal rails of negligible resistance rest 32 cm apart on a 6° ramp. The rails are joined at the bottom by a 0.60-Ω resistor. At the top of the rails, a copper bar of mass 0.040 kg and negligible resistance is laid across the rails and released from rest. When the copper rod reaches a steady speed, what will be (a) the...

The figure shows a 11-cm-long metal rod pulled along two
frictionless, conducting rails at a constant speed of 3.9 m/s. The
rails have negligible resistance, but the rod has a resistance of
0.65 Ω . (Figure 1)FigureThe figure shows a vertical rod sliding along a pair of
horizontal rails to the left at speed v. The rails are connected at
their left ends. Magnetic field B of 1.4 teslas is directed into

A pair of conducting, parallel, frictionless rails is mounted on an insulating platform. The distance between the rails is L=0.30 m. A light conducting bar 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, the rails are connected on one end by a R=1.5 resistor. A uniform magnetic field of B -0.25 T is...
