Lesson: Magnetic Field due to a Constant Current Loop
In this lesson, we will learn how to use the Biot–Savart law to determine the magnitude of the magnetic field produced by a loop of current-carrying wire.

A thin, non-conducting ring of radius 50 cm is free to rotate around the axis that passes through its center. The ring is charged uniformly with a total charge of 10 µC. If the ring rotates at a constant angular velocity rpm, calculate the magnetic field at a point on its central axis that is a distance 30 cm above the ring.
There is a current of 3.0 A in a square-shaped wire with sides each 3.0 cm long. What is the magnetic moment of the wire?
A current flows around a wire bent into the shape of a square of side . What is the magnetic field at the point that is a distance 30 cm above the center of the square?
