It is based on the idea that the potential difference develops at right angles to both the current and the field, and it is caused by the deflection of charge carriers by a magnetic field.
Its namesake probe can be used for the measurement of magnetic fields and in magnetically operated switching devices. Its namesake coefficient is equal to one over the number of charge carriers per unit volume times the electronic charge, and is designated by RH. It is based on the idea that the potential difference develops at right angles to both the current and the field, and it is caused by the deflection of charge carriers by a magnetic field. FTP, identify this law of electromagnetism that states that an e.m.f. is created whenever a transverse magnetic field acts on a current in a conductor.
