Consider a toroid of square cross section, with inner radius a = 2.0 cm and outer radius b = 3.0 cm, consisting of 125 turns of 18-gauge wire. toroidal multipoles—an elusive part of the dynamic multipole response [14-16]. The toroid has N turns and radius R. The toroid is narrow ( a≪R ), so the magnetic field inside the toroid can be considered to be uniform in magnitude. Consider a loop at a fixed radius inside toroid. 30. Numerical simulations of fully nonlinear visco-resistive magnetohydrodynamics are carried out to illustrate how the plasma dynamics are affected by shaping. dB. Applying Ampère's law in the same manner as we did in Example 13.8 for a toroid with a circular cross-section, we find the magnetic field inside a rectangular toroid is also given by [latex]B=\frac{{\mu }_{0}NI}{2\pi r},[/latex] where r is the distance from the central axis of the .
