First, in Fig. 118, note that the FLUX DENSITY inside the coil is greater, and more uniform, than it is at points outside the coil. Also note that not all of the generated ux passes through the entire interior of the coil; such lines are referred to as leakage ux; the lines labeled c represent such leakage ux. This e ect can be reduced by winding the turns closer together. In the gure, note that NORTH AND SOUTH MAGNETIC POLES exist at the ends of the coil. The nature of such poles (north or south) depends upon the direction of the current, and can be conveniently found by using the following right-hand rule :

If the ngers of the right hand curl around the coil in the direction of the current, the thumb points to the north pole. Note that Fig. 118 is drawn in accordance with the above right-hand rule. Also note the compass alignment in the gure ( unlike poles attract each other ). The arrangement of Fig. 118 constitutes an electromagnet. If the current i were reduced to zero i 0 , the magnetic eld would vanish. It is important to emphasize that WORK must be done to create the magnetic eld of Fig. 118. The work, so done, then remains stored in the magnetic eld as energy of the magnetic eld. If, later on, the current is reduced to zero, the magnetic eld collapses and the stored energy is returned to the circuit. Thus, since positive or negative work must be done, it is impossible to instantly change the state of a magnetic eld (just as it is impossible to instantly change the state of motion of a physical body).

All conductors possess what is called self-inductance. This is true regardless of whether the conductor is in the form of a straight wire, as in Fig. 117, or in the form of a coil of wire, as in Fig. 118 (although the e ect is much greater in the case of the coiled form of Fig. 118 than in the straight wire of Fig. 117). To understand the meaning of self-inductance, let us begin with the PRINCIPLE OF ELECTROMAGNETIC INDUCTION, discovered by Michael Faraday in 1831 (and, at almost the same time, by Joseph Henry in America). This famous principle states that A CHANGING magnetic eld generates an electromotive force. Notice that we emphasize the word CHANGING; if the magnetic eld in a region of space is constant, that is, not changing, then NO electromotive force is generated or induced in that region of space. But, as we have just learned in section 7.3, a MAGNETIC FIELD is generated by, and always accompanies, any ELECTRIC CURRENT. Thus a CHANGING ELECTRIC CURRENT generates a CHANGING MAGNETIC FIELD and therefore, by Faraday s principle, it follows that A changing electric current in a circuit induces an electromotive force in that same circuit. This is the phenomenon of SELF-INDUCTANCE, mentioned at the beginning of this section. Actually, in practical work the term INDUCTANCE is usually used instead of the longer term self-inductance. Thus, when we speak of the inductance of a coil, it will be understood that we mean self-inductance. It must be emphasized that inductance is a basic and very important component in electric circuit design. In practical work, required amounts of inductance are added to a circuit in the form of inductance coils, called inductors, as in Fig. 118. The greater the number of turns of wire, the greater is the amount of inductance possessed by such a coil.

If an extremely large amount of inductance is required, the wires are wound on an iron core. Next, the nature of the self-induced voltage that appears in an inductance coil can be summarized as follows. A self-induced voltage always appears at the terminals of an inductor coil whenever a CHANGE in the amount of current owing in the coil occurs. The POLARITY of the self-induced voltage is always such as to OPPOSE THE CHANGE IN CURRENT in the coil.* With the above in mind, let us now consider the following three possibilities concerning the state of the current i owing in an inductor coil: (a) a CONSTANT CURRENT is owing in the coil; (b) the current i is INCREASING in value; (c) the current i is DECREASING in value. A discussion of the above three cases, (a), (b), and (c), follows, in which the symbol represents an inductor coil. (a) If there is NO CHANGE in the value of the current, then there is no change in the magnetic eld and thus, by Faraday s principle, there is NO self-induced voltage induced into the coil. The energy stored in the magnetic eld of the coil remains constant, and zero voltage appears between the terminals of the coil. (b) Let it be given that a current i is owing in an inductor coil in the direction of the arrow in Fig. 119, and let it be given that the current is increasing in value.
