Experimental verification of quadrupole model of the electric field of a rotating magnet
We performed an experiment to verify quadrupole model of the electric field of a rotating magnet. It is found that the rotating magnet insulated from the earth and enclosed in a conductive insulated shield produces the potential difference across an air capacitor arranged on the outside of the shield. The field of the electric quadrupole cannot penetrate through the shield, therefore the electric field detected outside the shield is not quadrupole. The effect observed in the experiment can be explained by fictitious electric charge density inside the shield caused by the rotation of the magnet.
