Attraction and Repulsion Forces Between Magnets

AI Thread Summary
Calculating the attraction and repulsion forces between two magnets, such as Neodymium magnets, involves several factors, including their size, grade, and distance apart. The user has struggled to find specific equations or reliable resources for these calculations, noting that existing information often lacks clarity. They have explored the concept of superposition but have not found applicable equations for non-steel magnets. The discussion suggests that further insights may be available in the general physics forum, where more theoretical questions can be addressed. Overall, the need for clear methodologies in magnet force calculations remains a challenge.

How do you calculate the attraction and repulsion forces between two magnets? I know it depends on many factors, so for example: two 0.5"x0.5"x0.25" Neodynium magnets with a grade of 42 (Br = 13200 Gauss) that are 0.25" apart from each other (only air is separating them).

Thanks for any help in advance!

edit: **This is not a homework problem. After much research, I have been unable to find a way to calculate the forces between two magnets. It seems a lot of the science behind it is vague as of now. I have found one website that calculates these forces, but they don't list equations that are used. I tried to contact the company, but they haven't responded to me. I was wondering if anyone else had more insight into this.**

Is this a homework problem? If so you need to tell us some of your thoughts before we can help out. If not, perhaps you could repost in the general physics section (since you are free to get answers to hypothetical problems and questions there).

Superposition might be a good start.
 
It's not a homework problem. I reposted it in the general physics forum with some additional info.
 
In regards to superposition, I haven't found a good equation for the force from a magnet at a distance. I've found one for the force from a magnet on steel at a distance. However, the magnets I'm trying to use are not composed of steel.
 
Anyone able to help?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
