What is a typical wire diameter used to carry currents of thismagnitude in household or building wiring?R. What is the peak current?S. How can you compute the vector sum of the magnetic field mag-nitudes due to a large number of tiny segments of the currentloop?T. What magnitude of charge does the electron carry, and what isits inertia?with 20 A, 120 V circuits, so the available current will be on theorder of 20 A; O. enough to more than cancel Earth's magneticfield, say 4 X 10³T; P. 20 A for large appliances; Q. About 2 mmwire diameter; R. 105 A; S. by using the Biot-Savart law;T. e = 1.6 x 1019 C, m² = 9.11 × 10-31 kg; U. with 2-mm wirediameter, 500 turns per meter (or some small multiple of 500 turnsper meter, if the wire is wound in more than one layer) are possible;V. as a stack of horizontal current loops of different radii (careful:current depends on radius); W. 0.02 m.
