Would the magnet produce a better current if the copper wire was plated with silver?. I understand resistance and would be like to know if the resistance would be lower. Yes or no please, no answers saying I don‘t have the intellect to understand or that the problem I am trying to solve hasn‘t been solved by countless people with I. Q.‘s of 180. Thank you. Candid and honest answers are appreciated.
This is a very interesting question. I think others are missing the point. I believe what this individual is trying to ask is that if you plate copper wire with silver will the wire take on the more conducive properties of silver at less cost. Need the wire be solid silver? If you plated copper with silver about .001 of an inch it would be a relatively cheap process. Also you wouldn't have to use nickel. Silver will bond to copper quite well. Any Physics majors out there want to try to finger (figure) this one? I am a ME I'm not qualified to do the math on this one. However i can make a prototype!
When there is relative motion between a magnetic field and a conductor, current is induced in the conductor. The less the resistance of the conductor, the more the amount of current produced. Copper is a good conductor of electricity. Silver is a better conductor than copper. I doubt if silver plating would make much difference. A coil of wire will increase current flow. The more turns on the coil, the more the current flow. Increasing the speed of relative motion between the magnetic field and the conductor will increase current flow. Increasing the strength of the magnetic field will also increase current flow. And you must have a complete circuit for current to flow.
Bmw is the only outfit I know of that has come up with tubeless spoked wheels.
Correct to some extent! Completely correct if the wire is in form of a coil instead of an infinite length! If you know Lenz's lawyou'll know why! But a silver plating wont do any good. The phenomenon you're observing here is not a surface phenomenon but a completele bodily one. Instead if you replace the copper coil with a silver coil.results will be better. Silver is the best metallic conductorcopper is second best. If you are using a simple assembly like small bar magnets and a small coilcurrent produced is of the order of microamperes. To produce appreciable currents of the order of amperes, you will need superconductor magnets and thick coils.and the magnet should move at a high speed.
Not if you ride a BMW R1200GS. Otherwise, yes.
