Question

The current flowing through an inductor of self inductance L is continuously increasing. Plot a graph showing the variation of

Magnetic flux versus the current

Answer 1

Since ϕ = L I

where,   I = Strength of current through the coil at any time 
             ϕ =  Amount of magnetic flux linked with all turns of the coil at that time 
     and, L = Constant of proportionality called coefficient of self induction
