Hello,
I'm designing a magnetic device very similar to a speaker circuit (i.e. a bottom and top plate, a central pole, and a ring magnet). The only exception is that I'm adding an adjustable leakage path on the outside diameter, and inserting a coil in the empty space between the ring magnet...
I'm in need of a integrating flux meter. Does anyone know of one that is below $1000.00. I've been sampling the voltage at 5000Hz and digitally integrating, but I still I have some drift (1%of reading per second) that has been giving me a headache.
Hello,
I need to make a laboratory electromagnet that can produce an induction of ~1T over a 1"x1" area with an air gap of about 1" .
I have a small budget ~$1000. Which is why I think I'll have to make it. Can somebody give me a few pointers on what iron I should use? I know it should be of...
I need a rough idea of the field strength and gradient as a function of axial distance for a disk shaped perm magnet. I found a formula on the internet (http://www.magnetsales.com/Design/DesignG.htm) that I don't think is right. Shouldn't the formula be corrected for the demagnetizing field (...
