Science Experiments / Why does a magnet dropped through a copper pipe move so slowly?
« on: 24/03/2019 02:32:31 »
When a powerful rare earth magnet is dropped through a copper pipe it moves very slowly through it. Is it because the electric/magnetic field generated by the magnet in the copper pipe is in opposition to the magnetic field (like pole) or is it attraction (unlike pole) to the magnet? In other words is it attraction or repulsion that slows the magnet?
