When discussing magnetic fields we could say that
metals can become magnetic if they have many spinning electrons that create magnetic fields
O metals are magnets because they have more electrons than non-magnetic materials
O non-paired electrons spin in opposite directions creating a magnetic field
the spinning electrons in some atoms pair up and create a magnetic field
metal can become magnetic if they have many spinning electron. When the majority of atoms spin in the same direction the strong magnetic field is produced the direction of electron spin determine the direction of magnetic field
