In the accompanying figure, the rails, connecting end piece, and rod all have a resistance per unit length of . The rod moves to the left at v = 3.0 m/s. If everywhere in the region, what is tire current in the circuit (a) when a = 8.0 cm? (b) when a = 5.0 cm ? Specify also the sense of the current flow.
Why must pan of the circuit be moving relative to other parts, to have usable motional emf? Consider, for example, that the rails in Figure 23.11 are stationary relative to the magnetic field, while the rod moves.
Integrated Concepts A current balance used to define the ampere is designed so that the current through it is constant, as is the distance between wires. Even so, if the wires change length with temperature, the force between them will change. What percent change in force per degree will occur if the wires are copper?
Review. A novel method of storing energy has been proposed. A huge underground superconducting coil, 1.00 kin in diameter, would be fabricated. It would carry a maximum current of 50.0 kA through each winding of a 150-turn Nb3Sn solenoid. (a) If the inductance of this huge coil were 50.0 H. what would be the total energy stored? (b) What would be the compressive force per unit length acting between two adjacent windings 0.250 in apart?
A spacecraft orbiting the Earth has a coil of wire in it. An astronaut measures a small current in the coil, although there is no battery connected to it and there are no magnets in the spacecraft. What is causing the current?
Integrated Concepts Derive an expression for the current in a system like that in Figure 23.11, under the following conditions. The resistance between the rails is R, the rails and the moving red are identical in cross section A and have the same resistivity . The distance between the rails is l, and the rod moves at constant speed v perpendicular to the uniform field B. At time zero, the moving red is next to the resistance R.
Camera flashes charge a capacitor to high voltage by switching the current through an inductor on and off rapidly. In what time must the 0.100 A current through a 2.00 mH inductor be switched on or off to induce a 500 V emf?
Discuss the similarities between the energy stored in the electric field of a charged capacitor and the energy stored in the magnetic field of a current-carrying coil.
There is a voltage across an open switch, such as in Figure 21.43. Why, then, is the power dissipated by the open switch small?
A copper ring and a wooden ring of the same dimensions are placed in magnetic fields so that there is the same change in magnetic flux through them. Compare the induced electric fields and coffins in the rings.
Check Your Understanding Circuit breakers in a home are rated in amperes, normally in a range from 10 amps to 30 amps, and are used to protect the residents from harm and their appliances from damage due to large currents. A single 15-amp circuit breaker may be used to protect several outlets in the living room, whereas a single 20-amp circuit breaker may be used to protect the refrigerator in the kitchen. What can you deduce from this about current used by the various appliances?
Why is the power dissipated by a closed switch, such as in Figure 21.43, small?
