The unit of measure of the B field is guass or tesla. With a flux density calculator you plug in the length, width, and thickness, plus the relative permeability of the material you are using and the value returned is in gauss or tesla, the magnitude of the b field. I can't find any free...
Gentlemen, the the image shows 2 N48 neodymium magnets of the same volume 54 in2. On several website I can use magnetic flux density calculators to get the Br of the rectangular magnetic but haven't found one that calculates the value of the arc magnet. The Br value of the rectangular magnet is...
Gentlemen I want to apopogize for not stating what I want to know, but thanks to you all I understand much more than before, and I hope that now I can. I've been an avide reader of physics most of my life and recently have wanted to understand more.
This statement. Any arbitrarily small force...
I don't know how else to state that I want to know how much force is required to spin this flywheel at 3600 rpm's. If anybody knows the answer and doesn't mind please write the equation. I don't need to worry about drag and stress at this point.
Thanks
I am working on a project and the image you see is a 12 inch diameter flywheel that weighs 27.006 pounds. The RPM's will be 3600. My questions will be about the very large values I get for the acceleration and force. Since I am most familiar with ft/sec and pounds, those are the units I will...
Thanks everybody for the replies. E=mc2 looks a lot like F=ma to me. Since electromagnetic waves to not accelerate I'm curious as to why squaring the speed of light works in the equation. But correct me if I'm wrong please about the EM waves. It's my understanding that photons move at 300,000...
E=mc2. I am an avid reader of physics and science in general and a question popped into my head concerning the squaring of the speed of light in the equation E=mc2. It is my understanding that the speed of light is constant it does not accelerate. What rule or mechanism or whatever allows for...
