How Does a Solenoid's Magnetic Field Affect Electron Trajectories?

[dmsgo89]

Homework Statement

a solenoids is wound as shown and attached to a battery. two electrons are fired into the solenoid, one from the end and one through a very small hole in the side.*I can't attach the picture... so I tried to show you here.* ...... (-)electron 2
(-) ... ///////////// solenoid
electron 1 ... + - battery

electron 1 is going into the solenoid, from the left to right
electron 2 is going into the middle of solenoid, from the top to bottom
a) in what direction does the magnetic field inside the solenoid point?
b) is the electron 1 deflected as it moves through the solenoid? if so, in which direction? If not, why not?
c) is the electron 2 deflected as it moves through the solenoid? if so, in which direction? If not, why not?

Homework Equations

Right Hand Rule

The Attempt at a Solution

I hope you understood the thingy I tried to draw.

So, the solenoid's top parts going into the paper and bottom parts come out from the paper and the current flows from right to left (+ to -), using the right hand rule, the direction of the magnetic field inside the solenoids should go from the right to the left.

<- /////// -
... + - (battery)so, I said the the electron 1 which goes into the solenoid from left to right, should be deflected due to the its direction is against the direction of magnetic field of the solenoid.Then for part c), as it goes into the solenoid, I said it should follow the magnetic field's direction of the solenoid, moving to left as soon as it enters the inside of the solenoid.
However, I am not so sure of it.Can somebody fix this if it is wrong?

Thank you,

Hello,

I can confirm that your understanding of the direction of the magnetic field inside the solenoid is correct. The magnetic field inside the solenoid will indeed go from right to left.

For part b), you are correct in saying that electron 1 will be deflected as it moves through the solenoid. This is because the direction of the electron's motion is perpendicular to the direction of the magnetic field, causing it to experience a force and deflect in a direction perpendicular to both the electron's motion and the magnetic field.

For part c), you are also correct in saying that electron 2 will follow the direction of the magnetic field and move to the left as soon as it enters the solenoid. This is because the direction of the electron's motion is parallel to the direction of the magnetic field, so it will not experience a force and will continue to move in a straight line.

I hope this helps clarify your understanding. Keep up the good work!
