How can Gauss value be used to calculate magnetic force in Newtons?

AI Thread Summary
To calculate the magnetic force in Newtons using the Gauss value, one can convert the pull force from pounds to Newtons, resulting in approximately 146.8 Newtons for a pull force of 33 lbs. However, the discussion emphasizes the need for a formula that relates the Gauss value directly to the force at a specific distance from the magnet. While the conversion from pounds to Newtons is straightforward, the user seeks a method to utilize the Gauss measurement (3850 gauss) for force calculation. The conversation highlights a gap in understanding how to apply Gauss values in practical force calculations. Ultimately, a clear formula connecting Gauss to force in Newtons remains unspecified.

Hi, I'm buying magnets for a required experiment in my magnetic and electricity physics class. The supplier gives to important pieces of information: BrMax: 3850 gauss and Pull Force: 33lbs. I was wondering if there is a relatively simple formula so that I can calculate the force of the magnet at point x fromt he magnet using the gauss value. Essentially, I want to calculate the force of the magnet in Newtons. Thanks.

Divide pounds by .2248 and it will yield Newtons.

33 pounds / .2248 = 146.797153 Newtons



Multiplying Newtons by .2248 yields pounds.
 
Yes, I understandt hat but I want to know how to use Gauss to determine force in Newtons, if possible.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
