Inductance

What is inductance

• electric conductor or circuit that causes an electromotive force to be generated by a change in the current flowing.
  • the magnetic field is proportional to the current in the loop

• we can find inductance through

$$L\equiv \frac{{\Phi }_B}{I}$$

• L is the self inductance and its equal to the ration of flux and current

How to find inductance
