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!
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19.
For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Let's declare that for the cylinder,
mass = M = 10 kg
Radius = R = 4 m
For the wall and the floor,
Friction coeff = ##\mu## = 0.5
For the hanging mass,
mass = m = 11 kg
First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on.
Force on the hanging mass
$$mg - T = ma$$
Force(Cylinder) on y
$$N_f + f_w - Mg = 0$$
Force(Cylinder) on x
$$T + f_f - N_w = Ma$$

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is
The second part of the problem is exactly why you get this affect.
