Pulsed Power Supply -> Kinetic to Magnetic Energy

[jamie_sibley]

Can anyone give me some feedback on my understanding of this proposed experiment?

The device consists of 2 wound solenoids, each forming a closed loop.
One solenoid is slightly smaller as to be able to fit inside of the outer solenoid.

The smaller solenoid is accelerated by compressed air / gravity/ etc and allowed to fire through the outer solenoid.

If both solenoids we under the influence of a weak magnetic field, would the kinetic energy of the fired solenoid turn into magnetic potential energy stored in the generated magnetic field of the solenoids and provide a braking effect. I'm sure this would be the case if the projectile was a permanent magnet ( aka linear generator ), but I am not if it would work the same with 2 solenoids.

Also, could the outer solenoid then be used as a high current pulsed power supply, similar to a large capacitor, but using kinetic energy as input?

Your understanding of the proposed experiment is correct. The smaller solenoid will transfer its kinetic energy to the outer solenoid when it passes through, and this energy will be stored in the magnetic field generated by the two solenoids. This will provide a braking effect. Additionally, the outer solenoid can then be used as a high current pulsed power supply, similar to a large capacitor, using the kinetic energy from the smaller solenoid as input.
