Question

Consider a current carrying loop of wire. An electron is shotdirectly through loop's center perpendicular to the plane of theloop. What is the trajectory of the electron? Consider only themagnetic force here and no other forces. Curving away fromthe loop's axis.
Continuing straightwith no speed change.
The electron willcircle around the loop and back through the hoop's center again andagain in circular motion.
Continuing straightbut speeding up or slowing down depending on the direciton of thecurrent.

Explanation / Answer

   Continuing straight with no speedchange.    Since the direction of motion of electron issame as the direction of magnetic field, it will not experience anymagnetic force.
