Can an Electromagnet Produce 25T with 500 cm3 and How Much Current is Needed?

Click For Summary
SUMMARY

The discussion centers on the feasibility of designing a Bitter electromagnet capable of producing 25 Tesla (T) within a volume of approximately 500 cubic centimeters (cm³). It is established that while size does not limit the magnet's capability, the required current for such a magnet is substantial; for reference, a lab producing magnets between 20T and 45T indicates that their weakest DC field magnet operates at 17 megawatts (MW). The conversation highlights that increasing the dimensions of the magnet can maintain the same induction with the same electric power, emphasizing the importance of cooling in magnet design.

PREREQUISITES
  • Understanding of Bitter electromagnet design principles
  • Knowledge of Tesla (T) as a unit of magnetic flux density
  • Familiarity with DC field magnet specifications and power requirements
  • Basic concepts of electromagnetic induction and cooling mechanisms
NEXT STEPS
  • Research the design specifications of Bitter electromagnets
  • Explore the principles of magnetic flux density and its measurement
  • Investigate cooling techniques for high-power electromagnets
  • Examine the electrical power requirements for high-field magnets
USEFUL FOR

Engineers and physicists involved in magnet design, researchers in high-field magnet applications, and anyone interested in the technical specifications and challenges of producing high-Tesla electromagnets.

Hey guys, is it possible to design a Bitter eletromagnet that produces 25T and is approximately 500 cm3 in size? If so, how much current would it require? Thanks in advance for your responses guys..

I am not going to do the math but I will forward you to this article.

This lab builds 20T to 45T magnets and they claim their weakest DC field magnet takes 17MW. 25T is a very serious magnet.
 
Size doesn't determine the magnet's feasibility - "only" its cost...

You can increase or reduce all dimensions, including the experiment volume and the coil volume, and get the same induction from the same electric power.

Well, yes, a big magnet is easier to cool than a small one.
