The resistivity of BaTiO{sub 3}-based, positive-temperature-coefficient (PTC) ceramic materials is not significantly affected by applied magnetic fields at temperatures below the Curie temperature, {Tc}, but it increases with increasing magnetic field when temperatures exceed {Tc}. The rate of this increase diminishes gradually as the magnetic field is further increased. The magnetic field effects are stronger for magnetic fields parallel to than transverse to the electric current flow. A brief discussion of the experimental results is given.
