What happens when magnetic field cancel. Where do they go. Do they just vanish or return to the vacuum?
In a GFCI receptacle we have in most of our homes. The sense coil can output zero when there is deviation from net magnetic field between the line and neutral. This means the cancellation when the load appliance doesn't leak current is perfect. So there is perfect cancellation of the magnetic field within the sense toroid. So the magnetic flux just vanish, just like that? But energy can't be created or destroyed. Is it not?
