why intact
aluminum sheet stop quicker than pectinate one in the magnetic field?while swinging in the magnetic field, intact
aluminum sheets will formulate inner eddy current,that is the annular induced current.eddy current will transform the mechanical energy into heat energy, which makes the
aluminum sheet stop quickly.but pectinate
aluminum sheet can\'t formulate intact eddy current, so intact
aluminum sheet stop quicker than pectinate one.Other related question
