A thin metal rod of length L is rotating counterclockwise with an angular velocity omega on the plane of the paper about an axis through one of its ends, as shown in the Figure. A uniform magnetic field B_0 points into the plane in the region where the rod is rotating. Calculate the magnitude and direction of the magnetic force F_B that acts on the rod's charge carriers, resulting in the accumulation of opposite charges at the two ends of...
A conductive rod of 2 meters in length moves at 30 m/s in a direction perpendicular to a magnetic field B = 1 T. Determine the voltage produced between its ends.

2. A metal rod of length 15 cm is moving to the left though a magnetic field that points into the plane of the paper. The rod is moving with a constant speed of 1.8 m/s. The magnitude of the magnetic field is 0.26 tesla. a) . If you connected a voltmeter to the two ends of the metal rod, what would it say? (Be specific. Your answer should include a number.) b) According to your voltmeter, which is the...
Magnetic levitation A metal rod of length w = 15 cm and mass m = 85 grams has metal loops at both ends, which go around two metal poles (see the figure). m = mass of red ------ ------- The rod is in good electrical contact with the poles but can slide freely up and down. The metal poles are connected by wires to a battery, and a current I = 3 amperes flows through the rod. A magnet supplies...
A zero resistance rod is sliding west along two zero resistance rails that are 2.3 m apart, on the ground where the earth’s magnetic field is nearly vertical with a magnitude of 0.60 mT. the bar is moving with a velocity 60 m/s. As it moves through the earth’s magnetic field an EMF is generated that creates a current flowing through the rails. a far away western resistance completes the circuit with a 5 Ω. What is voltage difference across...
In the figure (Figure 1) a conducting rod of length L = 33.0 cm moves in a magnetic field B of magnitude 0.480 T directed into the plane of the figure. The rod moves with speed v=5.90 m/s in the direction shown. Part A What is the potential difference between the ends of the rod? Part B Which point, a or b, is at higher potential? Part C When the charges in the rod are in equilibrium, what is the magnitude of the electric field? Part D What...
A particle (q = 5.0 nc, m = 3.0 mu g) moves in a region where the magnetic field has components, B_x = 2.0 mT, B_y = 3.0 mT, and B_z =-4.0 mT. At an instant when the speed of the particle is 5.0 km/s and the direction of its velocity is 120 degree relative to the magnetic field, what is the magnitude of the acceleration of the particle?
A metal strip 6.50 cm long, 0.850 cm wide, and 0.760 mm thick

A conducting rod whose length is l = 30 cm is placed on a U-shaped metal wire that is connected to a light bulb having a resistance of 5.0 s as shown in the figure. The wire and the rod are in the plane of the page. A constant uniform magnetic field of strength 0.50 T is applied perpendicular to and out of the paper. An external applied force moves the rod to the left with a constant speed of...
