Lightest Strongest magnet I can buy

Click For Summary
SUMMARY

Dale seeks the lightest and strongest permanent magnet capable of producing a magnetic field greater than 5000 surface gauss. The discussion highlights neodymium magnets as the optimal choice due to their strength and lightweight properties. Participants emphasize the importance of considering the magnet's geometry and working conditions, particularly temperature limitations. Links to specific products, such as those from KJ Magnetics, provide actionable resources for sourcing suitable magnets.

PREREQUISITES
  • Understanding of permanent magnets and their properties
  • Knowledge of neodymium magnet specifications
  • Familiarity with magnetic field measurements (gauss)
  • Awareness of temperature effects on magnet performance
NEXT STEPS
  • Research neodymium magnet specifications and ratings
  • Explore the geometry of magnets and its impact on magnetic strength
  • Investigate the temperature limitations of permanent magnets
  • Visit KJ Magnetics for product options and detailed specifications
USEFUL FOR

This discussion is beneficial for engineers, hobbyists, and anyone involved in applications requiring lightweight, high-strength permanent magnets, particularly in fields like robotics, electronics, and material science.

Hi All,
I am wanting to buy the lightest, strongest magnet I can. Can someone please direct me or give me guidance on this issue? I am requiring a magnetic field of >5000 surface gauss. Any links or direction would be terrific,

Thanks in advance,
Dale.

Why not make a magnetic field by inducing a charge on some coils of wire, or would that be to heavy for what you want it for?

Hi Raul,
Thanks for your quick response. I require a permanent magnet. Yes the electromagnet would be far to heavy unfortunately. If I could get something like magnet paper with a strong magnetic field. This would be a very good solution.

Regards,
Dale.
 
Seems lie your best bet would be a neodymium magnet, but the ratings of you desire/what you get, would depend on the geometry of the magnet.

These might be your best bet, check what dimensions they have.

Temperature range might matter.

Hi Dale. Yes, I think one neodymium magnets can fit your need as of permanent magnets. However, you need to specify your exact working conditions as there will be limitation on working conditions of the magnets, especially for working temperature.
