if an emf is induced in a coil due to the current flowing through itself is called SELF INDUCTANCE.
on the other hand if an emf is induced on another coil due to the current flowing through the previous coil then it is called MUTUAL INDUCTANCE.
suppose there are two coils A and B
a current is flowing through A.
now if the flux produced due to this current induce an emf on the same coil A, then it is SELF INDUCTANCE, and if it produce emf on B, then it is MUTUAL INDUCTANCE due to coil A.

What is the main cause for the coefficient of coupling of a transformer being less than unity?
initially the induced emf i.e.,self inductance is high than mutually induced emf in the other .....so coefficient of coupling is high
What is self induced?
When a current in a coil increases or decreases, there is a change in magnetic flux linking the coil,an e.m.f. is induced. This is called self induced e.m.f. and the process is called self induction.
What is self referential structure?
It is exactly what it sounds like: a structure which contains a reference to itself. A common occurrence of this is in a structure which describes a node for a linked list. Each node needs a reference to the next node in the chain. struct linked_list_node { int data; struct linked_list_node *next; // <- self reference };
Why a three phase induction motor is self stating?
when you excite the 3-phase coils with an alternating supply,It produces a rotating magnetic field which interacts with the windings/conductor on the rotor & produces a current. According to Lenz's law the current induced is opposite in nature to the cause producing it & hence the magnetic field produced by this current will be opposite in nature to the rotating magnetic field in the stator.Hence due to interaction of these two forces a torque will be acting on the rotor which will make the rotor to rotate. Hence it is self-starting .
Example of automated system?
a automated system is any object which makes decision by its self without any humans interfering.
Is flow of induced current necessary when induces emf is being produced?
There is no such thing as an 'induced current'. Voltages are induced, not currents. If a voltage is self-induced into a coil, then that voltage will oppose any change in current. If a voltage is mutually-induced into a separate coil, no current will flow unless that coil is connected to a load.

What causes Russell's sign?
It is caused by self-induced vomiting
Origin of self directed work team and each example?
from where self directed team concept originated
What eating disorder involves self induced vomiting?
bulimia nervosia.
When did Eratosthenes die?
He died in 194 B.C. of self-induced starvation.
Is plasmolysis an example of active transport?
Osmosis is the tendency of fluid to pass through a semi-permeable membrane until there is an equal concentration of fluid on each side of the membrane. The fluid in not transported, movement is self induced
What are two types of EMF induced in a double wound transformer?
1. self- induction2. mutual- induction
What is an autotransformer?
An autotransformer is a transformer where the primary and secondary are a single winding.
What are the reasons why a current is induced in a coil?
Current is not induced into a coil. It's voltage that is induced into a coil. If the coil is connected to a load, or even short circuited, then a current will flow as a result of the induced voltage -but it's the voltage, not the resulting current, that's induced!Voltage is induced into a coil because the the changing magnetic field, due to the change in current (0 to Imax or vice versa) applied to that coil. The process is called 'self induction'.
