A plot of magnetic flux (phi) versus current (I) is shown in figure for two inductors A and B. Which of the two has larger value of selfinductance?

A plot of magnetic flux (phi) versus current (I) is shown in the figure for two inductors A and B. Which of the two has larger value of self inductance ?

If the magnetic flux linked with a coil through which a current of x A is set up is y Wb , then the coefficent of self inductance of the coil is

(a) Describe a simple experiment (or activity) to show that the polarity of emf induced in a coil is always such that it tends to produce a current which opposes the change of magnetic flux that produces it. (b) The current flowing through an inductor of self inductance L is continuously increasing. Plot a graph showing the variation of (i) Magnetic flux versus the current (ii) Induced emf versus dI/Dt (iii) Magnetic potential energy stored versus the current.
