What's Your Question?
Answer
Self inductance is the geometric property of a current carrying coil which causes the generation of back emf. We all know generation of back emf is directly related to change of flux through coil and we also know that flux linked is directly proportional to current though it. So mathematically self inductance is equal to magnitude of flux change when current in coil changes by 1 A/sec.
Answer

which a change in electric current in a circuit produces an induced electro-motive-force in the same circuit.

The self-inductance of a coil is said to be one henry if a current change of one ampere per second through a circuit produces an electro-motive force of one volt in the circuit.

Answer

Self-inductance is defined as the induction of a voltage in a current-carrying wire when the current in the wire itself is changing. In the case of self-inductance, the magnetic field created by a changing current in the circuit itself induces a voltage in the same circuit. Therefore, the voltage is self-induced.

Answer
Whenever the current flowing through a coil changes, an emf is generated across it. This induced emf is proportional to the change in current. ie EMF α dI/dt The constant of proportionality is called Self Indusctance (denoted by L) and measured in Henry. EMF =- L (dI/dt) The negative sign indicates the EMF generated is opposite to the flow of current
Answer

Whenever the current flowing through a coil changes, an emf is generated across it. This induced emf is proportional to the change in current.

ie

EMF  α dI/dt

 

The constant of proportionality is called Self Indusctance (denoted by L) and measured in Henry.

 

EMF =- L (dI/dt)

 

The negative sign indicates the EMF generated is opposite to the flow of current
