A permanent magnet works because OA) each atom has moving charge (orbiting electrons) - and moving charge generates a magnetic field B) the electrical current is moving charge (moving electrons) - and moving charge generates a magnetic field OC) moving charge doesn't really generate a magnetic field OD) by magic Moving charge generates a magnetic field. A) True B) False Moving charge generates a magnetic field. If the moving charge is in an already existing field, the fields will interact and the particle will experience a force. A) True B) False
