CONCEPT:
Self-Induction
  • Whenever the electric current passing through a coil changes, the magnetic flux linked with it will also change.
  • As a result of this, in accordance with Faraday’s laws of electromagnetic induction, an emf is induced in the coil which opposes the change that causes it.
  • This phenomenon is called ‘self-induction’ and the emf induced is called back emf, current so produced in the coil is called induced current.
  • Self-inductance of a solenoid is given by –
⇒ 
Where μo = Absolute permeability, N = Number of turns, l = length of the solenoid, and A = Area of the solenoid.
Given - l2 = 2l1
N2 = 2 N1
Self-inductance of a solenoid is given by:
⇒ 
⇒ 
⇒
L2 = 2 L1​
