direct proportional to current flowing through coil
directly proportional to the length
directly proportional to its area of cross-section
inversely proportional to its area of cross-section
Solution
Self-inductance: It's a property of a coil that opposes changes in the current flowing through it. It arises due to the coil's ability to induce an electromotive force (EMF) within itself when the current through it changes.
The formula \(L=N \Phi / I\) captures this relationship.
