What type of magnetic material has permeability less than 1?
Answer»
◆ this is the answer ◆ A paramagnetic MATERIAL has a constant relative permeability SLIGHTLY more than 1 . When a paramagnetic material, such as PLATINUM , is placed in a MAGNETIC field , it becomes slightly magnetized in the direction of the external field . A ferromagnetic material, such as iron, does not have a constant relative permeability .
