Can Electron Movement Be Controlled by Magnetic Fields?

AI Thread Summary
Electron movement can indeed be influenced by magnetic fields, as the conventional current flows opposite to the direction of electron motion in a wire. When analyzing two parallel wires with current, the same principles apply to the movement of electrons. The magnetic force on an electron can be calculated using the formula Fm = qvbsin(theta), where B is the magnetic field strength. Substituting the appropriate values for charge, velocity, and angle allows for accurate determination of the magnetic force. This confirms the relationship between magnetic fields and electron dynamics.

The current refers to the conventional current, opposite to the direction of motion of electrons in the wire, i.e., all electrons in the description moves in the same direction. Treat this as you do two parallel wires with current in them, then.

If I find out B of the wire, can I sub the q/v/sin theta of the electron into Fm = qvbsin theta to get the Fm then?

Beautiful. Thanks guys!
Here is what I tried
This question was actually asked in one of our engineering entrances.
The answer was 1D.
My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance)
My thoughts for the first case , one of them must be 12 volt while the other is 0
The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
The answer to this question is statements (ii) and (iv) are correct.
(i) This is FALSE because the speed of water in the tap is greater than speed at the water surface
(ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not?
(iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
