Higher magnetic-field generation by a mass-loaded single-turn coil

Area of Science:

• Physics
• Materials Science
• Engineering

Background:

• Single-turn coil (STC) technology enables the generation of ultrahigh magnetic fields exceeding 100 Tesla.
• STCs are prone to premature outward expansion due to Maxwell stress and Joule heating during field generation.
• This expansion limits the coil's performance, preventing it from reaching its full potential at maximum magnetic field.

Purpose of the Study:

• To investigate a simple method for delaying the expansion of single-turn coils.
• To enhance the maximum magnetic field generated by STCs.
• To improve the utility of STC technology for physical property measurements.

Main Methods:

• Development of a mass-loaded single-turn coil (STC) by incorporating clay.
• Experimental generation of magnetic fields using the modified STC.
• Analysis of the magnetic field profile and maximum field strength.

Main Results:

• The mass-loading of clay significantly altered the field profile of the STC.
• A notable increase of 4% in the maximum magnetic field was achieved.
• The expansion of the STC was effectively delayed, allowing for higher field generation.

Conclusions:

• Mass-loading STCs with materials like clay is an effective strategy to increase maximum magnetic field strength.
• This technique provides a practical and accessible method for achieving higher magnetic fields.
• The enhanced magnetic field capabilities can benefit various physical property measurements.
