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...

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...
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...

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 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.
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...
