I guess I have a rock in my head, I need help understanding what this produces and what it can be used for. Please reply so ASAP so I can gain a better understanding on the Hall effect, as I am currently working on a science project, which I believe involves the Hall effect.
You just made the first three weeks of my final year Electromagnetic Field Theory class seem like a walk in the park! Only if I had found this earlier... sigh
It's explicative, yet the Lorentz Force is F=Fe + Fb = q(vxB+E) so the force due to the electric field is the negative of that from the magnetic field (when equilibrium is reached). Also the product Vd B is a cross product. The lecture can be improved by either using vector quantities and vector products correctly, or by reducing the explanation to magnitudes of these quantities.
Your lectures are great! I was feeling a little too exhausted to be reading through the dense text in my book but needed to understand the material and your video really drove the point home! Thanks so much!
I was having a confusion regarding how the negative charges build up on one side and positive on the other side. This video cleared things up. Thanks a lot! :)
Great explanations, great information... i just wish you would put in some commas and periods between your sentences! Love the info in your videos, it's just hard for me to follow when the whole video sounds like a run one sentence. :/
awesome presentation!! I was finding bunch of stuff about the explanation and i could finally understand after watching urs!thanks!!!!! your presentation really made my day! :)
Sorry to be that person but the Lorentz Force (aka magnetic force) is the CROSS product of qv and B, not the dot product as is shown in this video. The dot product would be zero here since the velocity is perpendicular to the magnetic field. If written as scalars, not vectors, this notation would be correct though. Watch out with vector notations :))
I think you misrepresent that the vector product. It must be vd x B = E, where "x" stands for vector product. If it was vd*B = E, where "*" stands for dot product; then it will be wrong since dot product of two vectors cannot be a vector but a scalar.
What a cool explanation (lecture); but I wonder, what is the force that makes the electron move over the sheet of the metal initially, and where do the electrons that accumulate on the left-hand side of the metal come from?; (formerly you illustrated a single moving electron) but at the end, you showed many electrons accumulate at the left-hand side of the metal. Could you please explain it from the atomic perspective?.
can we use left hand rule to explain the induced force on the electrons as in index finger pointing out of the board, middle finger pointing to the left and thus the force represented by the thumb points upwards? (referring to the diagram at top right corner)
2:15 You say "The magnetic force will cause the electrons to travel closer to one side than the other. This will cause" a positive charge to appear on the other side How? are electrons being ripped away leaving a bunch of exposed protons that have a positive charge? is the magnet pushing protons together? are the deflected electrons attracting protons?
