Question
A beam of electrons is moving in a horizontal circle in a uniform magnetic field that is directed downward. The speed of the electrons is 1.0*10^7 m/s and the magnitude of themagnetic field is 1.0*10^-3 T.
As seen from above, are the electrons moving clockwise or counter clockwise?
What is the radius of the elecron's orbit?
What is the period of their motion?
I just can't understand the right hand rule. if anyone wants to try to explain it to me, I'd be grateful.
