Solenoid Problem...?
I have a solenoid which is originally designed to operate at 12 Volts DC. It has a resistance of 6 ohms. I need to make it operate using 48 Volts DC without loosing its original working conditions or magnetic strength. I also don't wanna re-wind it. Please help me. The current should be 2 A.

U need to drop of the excess 36V volt in an resistor.Since the current is 2A, connect a 18ohm(36V/2A) resistor in series with the solenoid.

ajk has it right, just make sure its rated for at least 75 watts and give it plenty of breathing room.
