Not illustrated. 1910 Excerpt: ...circuit. This property is called Self Inductance, when the momentary E.M.F. is induced in the same circuit in which the current change takes place. It is exactly like the induced E.M.F. which the property of Mutual Inductance sets up in another coil. The induced E.M.F. in each case obeys Lenz's law and tends to set up a current which shall oppose any change in the existing magnetic field. 166. Cause of Self Inductance. Make and Break Spark Coil. Consider Fig. 214. A current is made to enter at M. It first reaches the wire A. A field in growing around A cuts 43, and by the right-hand rule, induces an E.M.F. which tends to send a current Out. But a current of In is being sent through A3. This growing current of In in A3 is thus opposed by the E.M.F. of Oct induced by the growing field around A. Similarly, the current in A5 is opposed by an E.M.F. induced by the growing field around A3, and the current in A 4 by the growing field of current in A-2, etc. Also, if we consider the entire field within the coil, we sec that an E.M.F. is induced in the coil, which tends to set up a current opposing the building up of a field within it. Thus a growing current in such a coil is said to be "choked" back, and takes some measurable length of time to come up to the full value as expressed by Ohm's law. In a like manner, when the circuit is broken and the field around the wires and within the coil starts to die out, the wires are again cut by the field, though this time in a direction which sets up an E.M.F. tending to maintain the field and current as it is. D Make and If the magnetic field is sufficiently strong and the current is broken suddenly, the voltage induced by the dying field cutting the wires of the coil may be many times the original impressed volta...
