Lesson: The Magnetic Field of a Solenoid
In this lesson, we will learn how to use the Biot–Savart law and Ampere's law to calculate how the magnetic field of a solenoid varies with distance from the solenoid.

A solenoid is wound with turns per meter. When the current is 5.2 A, what is the magnetic field within the solenoid?
A solenoid with 25 turns per centimeter carries a current . An electron moves within the solenoid along a circular path that has a radius of 2.0 cm and is perpendicular to the axis of the solenoid. If the speed of the electron is m/s, what is ?
A solenoid has a ferromagnetic core with turns of conducting coil per meter wound around the core. The current in the solenoid’s coils is 5.0 A. The magnetic field inside the solenoid is 2.0 T. What is the magnetic susceptibility of the core material?
