👉 Magnetoresistance is a type of resistance that arises from the interaction between a magnetic field and an electrical current. It occurs when the magnetic field interacts with the electric current, causing it to change direction or speed. In other words, it's a phenomenon where the electrical current changes its path as a result of a magnetic field changing its direction or amplitude. This type of resistance is often used in devices that require high power and requires a strong magnetic field for operation, such as compasses or radar
