See what changing coupling coefficient does ;p .could anybody help me out on this 1 ??

Put the current on 3Hz, replace transformer and put on 1:2, put the resistor on 20ohm. It will work then.

Yes.but I was askig how coefficient of coupling would effect the transformation

Coupling coefficient is just like efficiency...If you have greater than 1 your circuit basically create energy out of nowhere...

Coupling coefficient is the percentage of the magnetic flux created from the primary coil that flows to the secondary coil...When you have coupling coefficient lower than 1 then not all of the magnetic flux created from the primary coil enters the secondary, some just take a path out of the core...in that case you gave flux linkage with means loses...

Thanks zefeirakis .that's what I was also thinking.apart from transform stepping up voltage.how do they just step it up.there are no losses due like when stepping it down

In the other hand if you have coupling coefficient greater than one (e.g. 1.19) that means that when the primary creates a unit of magnetic flux, 1.19 times more magnetic flux flows through the secondary, but what is the source of the 0.19 times extra flux...? In reality coupling coefficient greater of 1 is impossible...

In your case you have a positive feedback loop...Primary current creates a unit of flux and more flux enter the secondary which counterbalance the primary flux and more current flows through the primary witch creates bigger flux than before and that creates bigger secondary flux tha before witch create bigger current than before and so on so forth...

I hopped that help you...If you want check my circuit named "True Free Energy" based on that concept...

Yes IM LOOKING INTO IT

I wonder why the developer left the greater than one option

You cant have a coupling coefficient >1. That's what's the problem.

Try adding a current source after the resistor to make it a limiter and keep it stable
