Which statement correctly describes magnetism? (2 points) metals can become magnetic if they have many spinning electrons that create magnetic fields. metals are magnets because they have more electrons than non-magnetic materials. non-paired electrons spin in opposite directions creating an imbalance that creates a magnetic field. the electrons in some metals pair up to create a magnetic field.
