Question:
A toroid is a solenoid-like coil bent into a circle (Fig. 26.52a). Toroids are the configuration of choice in magnetic-confinement nuclear fusion experiments, which, if successful, could provide us with an almost unlimited energy source using deuterium fuel extracted from seawater.
The ITER consortium, an international collaboration, is building a large toroidal fusion experiment in France; it?s expected to be the first fusion device to produce energy on a large scale. Figure 26.52b shows a cross section of a toroid, with current emerging from the page at the inner edge and descending at the outer edge. The black circle is an Amperian loop
The magnetic field associated with the toroid is nonzero?a. only within the ?hole? in the donut-shaped coil.?b. only within the region bounded by the coils.?c. only outside the coils.?d. everywhere.
