Distance to which magnets start attracting each other

Click For Summary
SUMMARY

The discussion centers on calculating the distance at which two Neodymium Magnets N52 begin to attract each other. The user seeks a formula to determine this distance based on their specific magnets, which have a radius of 0.5 inches and a length of 1.5 inches. It is established that magnets interact at all distances, but the strength of attraction diminishes as the distance increases. The orientation of the magnets also plays a crucial role in determining whether they attract or repel each other.

PREREQUISITES
  • Understanding of magnetic field strength and distance decay
  • Familiarity with Neodymium Magnets, specifically N52 grade
  • Basic knowledge of magnet orientation and its effects on attraction
  • Ability to interpret formulas related to magnetic interactions
NEXT STEPS
  • Research the formula for calculating magnetic force between two magnets
  • Explore the properties of Neodymium Magnets, focusing on N52 specifications
  • Learn about the effects of distance on magnetic field strength
  • Investigate the orientation of magnets and its impact on attraction and repulsion
USEFUL FOR

Students, engineers, and hobbyists interested in magnetism, particularly those working with Neodymium Magnets and seeking to understand their interaction dynamics.

Hi, I was wondering whether it was posible with a formula to measure the distance to which two equal magnets start attracting to each other. I was looking at this web page https://www.kjmagnetics.com/blog.asp?p=surface-fields-101 and I am not sure if this is the right formula.

I have two Neodymium Magnets N52 with a radius of 0.5" and a length of 1.5". I am looking for a formula because I need to order more magnets and I need to know this before I order more. Thanks

Any help or comment is appreciated.

Daniel

They always interact regardless of the distance, although thte strength gets weaker with distance. Whether they attract or repulse each other depends on their orientation.
