2 for such conductors). 124. Skin effect in conductors of magnetic materials is much greater than in those of non-magnetic materials owing to the stronger magnetic field that a given current will set up in a magnetic metal. 125. The effect of inductance in an ac circuit is that it produces opposition to the flow of the current and tends to make the current lag behind the voltage in time or phase. If a pure inductive circuit (one with only inductance and no resistance) could be built, the current would lag 90 degrees, or 1⁄4 cycle, behind the voltage.

76. Thermal action produces emf’s in the following ways: 1. Seebeck effect. 13 EMF generated by heat. different metals are kept at different temperatures (see Fig. 13). Thermocouples function through this phenomenon. The magnitude of the emf produced will depend upon the material of the metals and the difference in temperature between the hot junction and the cold ends. Since only very small voltages can be produced in this way, the method is not applicable when electrical energy of any quantity is required.
