Hi jaskiratubhi,
I will not even try to comment your circuit, not feeling expert enough. I'll just say, that I think "simultaneously switching) it probably not a good idea and is very hard (if not impossible to realize).
But the first circuit is actually basic physics, and this spike can be easily realized. Just throw out the right part of the circuit, and put a large resistor in parallel to you coil. This way when the switch is opened, coil will discharge through this resistor. You can vary it's value to alter the spike.
You can even do it without the parallel resistor, but only if you can tell what the spike will be with open circuit. This is the case with automotive injectors, for example. The spike is clearly seen when injector is switched off and the spike is under 100 V normally.
