You are given a solenoid of length 'l', number of turns per unit length 'n' and area of cross-section A. When a current 'I' passes through it, a. What is the total magnetic flux through the solenoid? b. What is the self inductance of the solenoid? c. How does the value of self inductance get affected if some material of high relative permeability is filled inside the solenoid? |
