Suppose the rod is moving with a speed of 5.0m/s perpendicular to a 0.80-T magnetic field. The rod has a length of 1.6 m and a negligible electrical resistance. The rails also have a negligible electrical resistance. What is the magnitude of the mechanical force needed to achieve that? Make sure you include the unit with your answer. Answer:

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...

A metal rod is connected to a battery through two stiff metal wires that hold the rod horizontally. The rod is between the poles of a horseshoe magnet that is sitting on a mass-measuring platform scale, which reads 100.0 gg. After you turned on the current in the circuit, the scale supporting the magnet read 106.0 gg. The part of the rod that is exposed to the magnetic field is 6.0 cmcm long and the current through it is 1.5...

Consider a 16.5 cm long metal bar moving horizontally across a vertical magnetic field at a speed of 7.4 m/s. The magnetic field strength is 2.45 T. If the ends of the bar are connected to a 18.2 ohm resistor, find the power dissipated in the resistor while the bar is moving. Calculate the answer in watts (W) and rounded to three significant figures please. :)
There is a uniform magnetic field of magnitude B, pervading all space, perpendicular to the plane of rod and rails.
There is a uniform magnetic field of magnitude B, pervading all space, perpendicular to the plane of rod and rails. The rod is released from rest, and it is observed that it accelerates to the left. In what direction does the magnetic field point?a) A conducting rod is free to slide on two parallel rails with negligible friction. At the right end of the rails, a voltage source of strength V in series with a resistor of resistance R makes...

You are given a circuit with a switch, resistor, capacitor and battery all in series. The capacitor is initially discharged and begins charging at t=0.0000s, when the switch is closed. The capacitance is C=0.0100F, the resistance is R=80.0000Ohms, and the battery EMF-15.0000 Volts. At what time is the voltage across the capacitor half the maximum? (in seconds) Your Answer: Answer A uniform magnetic field points toward the right. The direction for a positive moving charge is 1.0000, where "1" means...
