1. Introduce – Permalloy – An alloy with soft magnetic and magnetic shielding properties * Permalloy √ An alloy typically containing about 80% Ni and 20% Fe √ An alloy characterized by very high permeability and low magnetic hysteresis loss * Soft magnetic materials √ Highly permeable materials characterized by high permeability and low coercive force – Permeability: A measure of the degree to which magnetization occurs when an external magnetic field is applied – Coercive force: The strength of the external magnetic field required to reduce the magnetization of a ferro...
