A toroid is a coil of wire wrapped around adoughnut-shapedring (a torus). For a tightly wrapped toroid with N turns, the magnetic field lines of Bformconcentric circles inside the toroid, and the field is zero outside. Use Ampereâs law to find an expression for the magnetic field strength B at a radial position r from the axis ofthetoroid.
