hello??

so how would i do that? the speed at which the coil cuts fields? can you like just give me a worked out example, using whatever numbers you want.

if you can help some more id really appreciate it

ok. im trying to generate current by cutting magnetic fields with wiring coiled around an iron core. all i want to know is how much current I am going to get and the voltage too.

Help with Gauss To calculate the voltage induced when cutting magnetic field lines you need to know the strength of the magnets in Gauss. I was looking at some magnets I would like to buy for a project. The magnets had 2 different values for the gauss. "Brmax (Residual Induction) or...

wait no that's not what i meant. im confused. what you're saying has a magnet cut the field lines. what i was thinking was the field lines could be cut by the coil, is that possible? i mean can i place two magnets side by side, and drop a coil of wire in between them to induce voltage?

Ok thanks, you've been a lot of help. Its the upper right picture in Doc Al's link, the one in which you move a magnet in a coil

oh ok. so let's just see if i get it. to calculate the induced voltage, you check the area of the field, you multiply it with the strength of the magnet, divide by the speed of the wire and multiply by the number of turns of the wire. wait, what are the units? B is in Tesla, right? but...

ok so wait, does the radius of the coil include the diameter of the wiring? or is it just the area within the coil, and not including the wire

ok. but how do you find the area of the coil?

hmm that looks good, but how do you get "A" ? oh and why is there a negative sign?

Induced Voltage = -NBA/t I know the equation, but could someone please explain it to me?

Ok so I'm working on a project involving magnets and inducing current. Thing is that I'm on a budget and need to make sure that I buy the right things. For my project I'm going to need neodymium magnets. Using the magnets I'm going to induce current. I found a website selling magnets. It...

*BUMP* I'd appreciate it if someone could help, this things killing me. oh and thanks Bob and Pgardn [ ^o), "Pgardn"? ]

Ok, I think I get it. But how would you know which side is positive and which side is negative? How would I connect it to the capacitor? I realize, there's no point in doing this, its just something that I'm interested in. Oh and, around how much electricity would moving the wire across...
