Magnet Simulaiton without Newton

[Esther Podrasa]

Does anyone know how to make a physics magnet simulation without the Newton Plug-In? Similar to this: https://i.pinimg.com/originals/73/c4/e3/73c4e3db9f1b3730d1737fd980e2df30.gif

I think if you google search for “proximty expression” you’ll see quite a few variations on pulling objects towards a point. You might need to go further and have then retain that position, or you could probably use mutiple hidden points and leave them in place.
