magnetoresistance

Magnetoresistance is the phenomenon where the electrical resistance of a material changes when a magnetic field is applied. In simple terms, the magnetic field influences how electrons move through the material. Depending on the material's properties and the magnetic field's strength, resistance can increase or decrease. This effect is useful in various technologies, such as magnetic sensors and data storage devices, because it allows for the detection or manipulation of magnetic fields through electrical signals. Essentially, magnetoresistance reveals how magnetic fields can control the flow of electricity within certain materials.
