Best ResponseYou've already chosen the best response.0u know that hand rules?

anonymous

Best ResponseYou've already chosen the best response.0I do. The right hand rule is the name given to a few different things. In Electricity and Magnetism (E and M, or EnM, for short), it usually refers to pointing your thumb in the direction of the positive current, and your fingers will curl around in the direction of the magnetic field.

Best ResponseYou've already chosen the best response.0Another version of the right hand rule involves pointing fingers in the direction of vectors in a cross product. You can then find the direction of the result by doing this. Example: A x B = C (A cross B) If you point your index finger in the direction of A (keeping the index finger straight), and your middle finger in the direction of B (flip your hand if you need to point in a direction on the back side of your hand), then the result of the cross product will be in the direction your thumb is pointing (if using the right hand).

Best ResponseYou've already chosen the best response.0Correct, you can do the same thing with your left hand for an electron (negative current)

Best ResponseYou've already chosen the best response.0how is that possible

anonymous

Best ResponseYou've already chosen the best response.0It's saying that a negative charge would build up on that side, because the electrons would move that direction.

Best ResponseYou've already chosen the best response.0For this, we use the cross product hand rules. \[\vec{F} = q\vec{\rm{v}}\times \vec{B}\] q is the charge of the particle. For an electron, this is a negative number. We can account for this by using our left hand. Since v comes first in the equation, we point our index finger in it's direction (upwards). Keep the hand aligned with the index finger, as much as you can. B comes next. We'll point the middle finger in the direction of B (to the rightish). Then, stick out your thumb. Your thumb should be pointing towards B (back toward youish) This doesn't tell you the magnitude of the force, but your thumb is pointing in the direction of the force on the electron. Electrons would move towards point B, causing that side of the rod to become negatively charged.
