Description
Wanli Fan and co-authors measure the magnetic pull inside an aircraft engine seal in a 2024 study. The seal holds a spinning ring against a magnetic fixed ring; too little force and it fails. The team computed the force with a stress tensor method in a finite element model, then checked the numbers on a test bench across magnet setups and gaps.
Of four magnet materials, the neodymium type pulled strongest and a samarium type came second; the other two managed only a fifth to a quarter as much. Pull also swung with magnetization direction, the axial mode more than doubling the radial one. The authors map choices for moving parts.
