How do you draw phase diagram for transformer operating at load with lagging PF and leading PF?
In order to draw the phase diagram for transformer operating at load with lagging PF and leading PF, you will need to know the equation for the transformer being load free. This constant will help you with the load bearing equation of Np/Ns=Vp/Vs=Is/Ip.

How emf induce while apply in primary side of the transformer?
when an alternating current apply on primary side of transformer then magnetic flux produced in the iron core of transformer.Then flux link with secondary winding of transformer so that an emf produced in a transformer.
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
If the primary winding of a double wound transformer is supplied with the direct current its iron core will become magnetized but there will be no emf induced in the secondary winding?
BECAUSE YOU NEED AC EFFECT TO INDUCE EMF IN TO SECONDARY WINDING.OR DC PULSING.
Why Back EMF occur in only dc motor?
It doesn't. It exists in all electrical machines, d.c. or a.c., motor, generator, or transformer.

What equation best describes the induced emf due to the movement of a rod in a magnetic field?
The equation that best describes the induced emf due to the movement of a rod in a magnetic field is given by Faraday's Law of Electromagnetic Induction, which states that the induced emf () is equal to the rate of change of magnetic flux () through the loop formed by the rod. Mathematically, it can be expressed as -d/dt.
Why is emf generated when magnetic flux is cut by a conductor?
See related links below. There is a lot of technical jargon there but look at the motor and transformer section.
