Magnetoresistance
Magnetoresistance is the property of some materials to change the value of their electrical resistance when an external magnetic field is applied to them. The effect was first discovered by William Thomson in 1857, but he was unable to lower the electrical resistance of anything by more than 5%. This effect was later called ordinary magnetoresistance (OMR). More recent researchers discovered materials showing giant magnetoresistance (GMR), colossal magnetoresistance (CMR) and magnetic tunnel effect (TMR

Magnetoresistance is closely connected to Electromagnetism
The resistance that a unit of current encounters while passing through an electromagnetic circuit is termed as Magnetoresistance
The magnet's resistance to the current flowing through the conductor is also termed as magnetoresistance
