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!
Neglect gravity other than that of water; neglect friction.
F1=ρgsh=1000*10*1*(1+4)=50000 N;
F1=ρgsh=1000*10*0.1*4=4000 N;
F3=50000-4000=46000 N?
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system
$$M(t) = M_{C} + m(t)$$
$$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$
$$P_i = Mv + u \, dm$$
$$P_f = (M + dm)(v + dv)$$
$$\Delta P = M \, dv + (v - u) \, dm$$
$$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$
$$F = u \frac{dm}{dt} = \rho A u^2$$
from conservation of momentum , the cannon recoils with the same force which it applies.
$$\quad \frac{dm}{dt}...
I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are;
Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction.
Must be LESS than 1 kg.
NO parachutes.
NO glue or Tape can touch the egg.
MUST be able to take egg out in less than 1 minute.
Grade A large eggs will be used.
