The shielding property of cylinder with circular, square, and equilateral triangle holes was investigated by finite element analysis (FEA). hole area ( S ) plays an important role in magnetic circuit on the surface cylinder. When is less than critical H ), three shapes obtained same remanent magnetization inside, indicating that unaffected shape hole. Hence, high-permeability material major path field. On condition > , sequence square resulting from magnetoresistance leakage flux air...
In this paper, the influence of rectangular holes with different aspect ratios in a cylinder on shielding properties is investigated using finite element method. The two indicators used to assess are its internal residual magnetic field and outer-surface map. (B) as function ratio hole area simulated, conclusions follows: increasing length hole, value B increases first then decreases. A cylindrical shield square (the equal 1) delivers worst performance. smaller has better properties,...
