Lesson: The Magnetic Field of a SolenoidPhysics
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.
Sample Question Videos
The current through a solenoid is 2.0 A. How many turns per centimeter must be wound on the solenoid in order to produce a magnetic field of T within it?
A solenoid is wound with 2,000 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 ?
