Does the aluminum foil tray is magnetic material?
The research shows that the external magnetic field of any material may be influenced more or less by magnetization.In accordance with the performance of magnetization,there are five kinds of materials:paramagnetic material,diamagnetic material,ferromagnetic substance,sub-magnetic material and diamagnetic material.Generally speaking, the magnetic material refers to the alloy which produces magnetic material directly or indirectly,like metal,cobalt,nickel,ect..Aluminum belongs to this kind of material.
