A toroid is a solenoid bent into the shape of a doughnut. It looks similar to a toy Slinky® with ends joined to make a circle. Consider a toroid consisting of N turns of a single wire with current I flowing through it.

A wire with resistivity ρ (resistance per unit length) is bended in a way to form a shape like bb-8 in the movie Star Wars. (See the figure on the right.) We can approximate it as two circles of radius R and 2R lying in the same plane. Note the wire has an insulating shell, and it crosses over itself at joint of the two circles. The wire is then placed in a magnetic field that is spatially uniform, but increases its magnitude over time with B = bt, where b is a constant of appropriate dimension.
