Lesson: Magnetic Field due to a Constant Current LoopPhysics
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.
Sample Question Videos
The current through a circular loop of conducting wire is 6.0 A and the magnitude of the magnetic field at the center of the loop is T. What is the radius of the loop?
A flat, circular loop has 20 turns. The radius of the loop is 10.0 cm and the current through the wire is 0.50 A.
Determine the magnitude of the magnetic field at the center of the loop.
Two flat circular coils, each with radius and wound with 30 turns, are mounted along the same axis so that they are parallel and 1.5 m apart. What is the magnitude of the magnetic field at the center of either coil at the common axis if a current flows in the same direction through each coil?
