Question

A long solenoid has 100 turns/cm and carries current i. An electron moves within the solenoid in a circle of radius 2.30 cm perpendicular to the solenoid axis. The speed of the electron is 0.0460c (c = speed of light). Find the current i in the solenoid.

Solution

The orbital radius for the electron is r=mveB=mveμ0ni

which we solve for i:
i=mveμ0nr=(9.11×1031kg)(0.0460)(3×108m/s)(1.60×1019C)(4π×107T.m/A)(100/0.0100m)(2.30×102m)=0.272A
