I have an experiment that I'd like to try. I have all the parts, except for this.
It calls for an electromagnet that has 500,000 gauss, at 17 Hz, square wave, at 40-60% duty cycle. I think the gauss could be less, maybe. who knows anything? Where could I get something like this? What might it cost, roughly?

500,000 Gauss? I don't think the guides in billion-dollar particle accelerators produce that much. I think the safety limit on MRI's is something like 50,000.
I'm trying to imagine what experiment you could be trying to replicate...

quote:The overall quantity, or amount, of magnetism produced by a magnetic object or device is measured in webers (Wb). A smaller unit, the maxwell (Mx), is used if the magnetic field is weak. One weber is equivalent to 100,000,000 (10^8) Mx. Conversely, 1 Mx = 0.00000001 (10^ -8) Wb. Flux density is a more useful expression for magnetic effects than the overall quantity of magnetism. A flux density of one tesla (T) is equal to one weber per square meter (1 Wb/m^2). In this case, we can imagine each flux line as 1 Wb. A flux density of one gauss (G) is equal to one maxwell per square centimeter (1 Mx/cm^2). In this case, we can imagine each flux line as 1 Mx. One gauss is equivalent to 0.0001 (10^-4) T. Conversly, 1 T = 10,000 (10^4) G.

This probably doesn't help much, but that's as detailed a description of "gauss" as I could find.
