If the current in the coil is increasing (by the change in circuit conditions), the self-induced emf is produced in the coil in such a direction so as to oppose the rise of current, that is, the direction of self-induced emf is opposite to that of the applied voltage. On the other hand, if the current in the coil is decreasing, the self-induced emf is produced in the coil in such direction so as to oppose the fall of current. In other words, the direction of self-induced emf is in the same direction as that of the applied voltage. In fact, self-inductance does not prevent the change of current, but it delays the change of current flowing through a coil.<\/p>\n\n\n\n<p id=\"para-430\">It may be noted that this property of the coil only opposes the changing current (<em>i.e.,<\/em>&nbsp;AC). However, it does not affect the steady (<em>i.e.<\/em>, DC) current when flows through it. In other words, the self-inductance of the coil (by virtue of its geometrical and magnetic properties) will exhibit its presence to the AC, but it will not exhibit its presence to the DC.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h4-009\">5.20.1&nbsp;&nbsp;Expressions for Self-inductance<\/h4>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/learning.oreilly.com\/api\/v2\/epubs\/urn:orm:book:9789332558311\/files\/images\/page240_3.png\" alt=\"image\"\/><\/figure>\n\n\n\n<h5 class=\"wp-block-heading\" id=\"h5-022\">5.21&nbsp;&nbsp;MUTUAL INDUCTANCE<\/h5>\n\n\n\n<p id=\"para-431\">The property of one coil due to which it opposes the change of current in the other (neighbouring) coil is called mutual inductance between the two coils.This property (<em>i.e.<\/em>, mutual inductance) is attained by a coil due to mutually induced emf in the coil, while current in the neighbouring coil is changing.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h4-010\">5.21.1&nbsp;&nbsp;Expression for Mutual Inductance<\/h4>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/learning.oreilly.com\/api\/v2\/epubs\/urn:orm:book:9789332558311\/files\/images\/page240_4.png\" alt=\"image\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The property of a coil due to which it opposes the change of current flowing through itself is called self-inductance or inductance of the coil.&nbsp;This property (i.e.,&nbsp;inductance) is attained by a coil due to self-induced emf produced in the coil itself by the changing current flowing through it.
