Nice ;P

thanks

как это работает???

Please dont speak in russian!
But it works using scripts to simulate the current, the charging and the magnetic field.
And the working in real life: Charge is stored in a capacitor, when it is charged a switch is closed to complete the circuit, all the eletricity that was stored in the capacitor flows in a stronger and faster pulse of energy through the coil this creates a magnetic field that generates a eletric current in the metal then this current creates a magnetic field with the same polarity of the original field, this causes repulsion that causes the metal to crush.

i dont get how you made this :?

OMG ! I just used script
