Worksheet: Magnetic Field of a Toroid
In this worksheet, we will practice using the Biot–Savart law and Ampere's law to calculate the magnetic field produced by a toroid.
A toroid has an inner radius of 20.0 cm and an outer radius of 22.0 cm. The toroid is tightly wound with one layer of 0.250-mm-diameter wire.
How many turns are there on the toroid?
If the current through the toroid windings is 2.0 A, what is the strength of the magnetic field at the center of the toroid?
