Unformatted text preview: magnetic ﬁeld is 0 . 3 × 104 T at the height of the satellite. Calculate the voltage diﬀerence between the ends of the wire. (In the NASA experiment, the tether broke, melted, or failed somehow, but collected data demonstrated potential for power generation.) 2. Griﬃths 7.8 3. The alternator in a car consists of a rectangular coil with 250 turns of wire and area 0.01 m 2 rotating in a 0.1 T magnetic ﬁeld. If the rotation rate is 1000 rpm, what is the peak output voltage? 4. Griﬃths 7.18 5. Griﬃths 7.20 6. Show the the mutual inductance of an inﬁnite wire and an equilateral triangle, as pictured below, is M = μ π √ 3 h ( a + b ) ln ± 1 + a b ²a i (1) b a inﬁnitely long wire 7. Griﬃths 7.32 8. Griﬃths 7.50 (This problem will make you think twice about wiring meters into a circuit. Do you understand why the answer is what it is?) 9. Griﬃths 7.54 10. Griﬃths 7.58 1...
