And Del adds :

But electricity is not the only way of acting on something from a 
distance. Pneumatics or hydraulics, for example, could do the trick. 
We know about electricity being banned from Hogwarts, but we don't 
know of anything else.

And as an ex Physics student, I'd be dead interested to know how ever 
they managed to make the castle impervious to electricity. Ideas 
anyone ?
