Design   
Halbach array achieved an ideal state of One-sided flux in this linear magnet design. It realizes a strong magnetic field on one side while creating a very small stray field on the opposite side.

Sizes   
• 8.12" thru 13.7" OD   
• 25.2" thru 39.6" L

What is a Halbach array advantages?   
Halbach array creates a strong, unidirectional magnetic field while cancelling the field on the opposite side.   
• high field concentration   
• reduced stray magnetic flux   
• higher magnetic efficiency   
• improved safety by minimizing unwanted magnetic field   
• more compact assembly design that saves space and weight

Applications   
Remove ferrous debris in the tool run area   
• a part of the drill string   
• deep wells   
• wells with excessive metal debris   
• fishing and milling

Features   
• Magnets embedded in a steel casing    
• Full 360° stabilization   
• Magnetic field 10000-12600 Gauss   
• High temperature rating 120-200℃
