In e/m experiment when angle between v and B is not 90 then why electron follow a helical path?

A moving charge is an electric current.

Get that through your head. A lot of people think they are established scientists but they never learned that fact and they are totally flummoxed when they observe an electrical phenomenon. For example scientists have been told that charged particles power the northern lights, but they don't realize that a charged particle in motion is an electric current. So when someone mentions that the jet wind is an electric motor powered by current from the sun, they don't know what he is talking about.

Ok, so an electric currenty generates a magnetic field. A magnetic field causes the electron to move. Put the current, field, and motion together and you have a spiral. If the impressed field is at a right angle, the spiral is a circle.
