Two resistanceless rails rest 29 cm apart on a 4.5 ∘ ramp. They are joined at the bottom by a 0.80 Ω resistor. At the top a copper bar of mass 0.065 kg (ignore its resistance) is laid across the rails. The whole apparatus is immersed in a vertical 0.70 T field.
What is the terminal (steady) velocity of the bar as it slides frictionlessly down the rails?

a) A simple generator has a square armature 5.0 cm on a side. The armature has 95 turns of 0.59-mm-diameter copper wire and rotates in a 0.650-T magnetic field. The generator is used to power a lightbulb rated at 12.0 V and 25.0 W. At what rate should the generator rotate to provide 12.0 V to the bulb? Consider the resistance of the wire on the armature. b) Two resistanceless rails rest 23 cm apart on a 6.0∘ ramp. They...

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...

QUESTION 15 Two rails are attached to a 150 incline plane 50 cm apart as shown in the figure. A copper bar with a diameter of 2 cm is placed on top of the two rails. (The density of copper is 8960 kg/m and the resistiyty of copper is 1.68x10-8 m). There is a 0.055 T magnetic field oriented perpendicular to the plane of the incline through the entire setup. The copper bar slides down the rails at a steady...

A conducting rod of length 4.5 m is sliding downward between two vertical rails without friction. The rails have negligible resistance, but the resistance of the rod is 0.8 Ω. The rails are connected to an 23.3-Ω resistor, and the entire apparatus is placed in a 0.1-T uniform magnetic field. The rod is sliding down at the constant velocity of 7.4 m/s. What is the value of the constant current generated in the rod?

Two parallel conducting rails with negligible resistance are
50.0 cm apart and are connected together at one end by an 16.8-Ω
resistor. A conducting bar, also with negligible resistance, is
free to slide along the rails. The system is in a region where a
425-mT magnetic field points perpendicular to the plane of the
rails, as shown in (Figure 1).
How fast should the bar be pulled in order to produce a current
of 0.150 A?
