"Electro couplers" for G scale?

[homersimpsonlikestrains]

I know Lionel has Electro couplers for their high end line of trains, but does anybody know if there are any "electro couplers" available for G scale? I want to be able to couple and decouple train cars by pressing a button on a remote controller.

You can probably get or make an electric magnet to uncouple the G scale Kadee couplers. I don't remember seeing any commercially available ones.

i made some very cheaply [under one dollar] for HO DCC, i would imagine that they are available for your scale
