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 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
