5 By vaporizing a material into ions, mass spectrometers can tell what elements make up that material. When a magnetic field is applied to ions, they deflect or accelerate various amounts depending on their electric charge to mass ratio. By observing how much the ions deflect, the mass spectrometer can identify the charge to mass ratio of each ion and thus which element it is.

6 Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets. When a ferromagnetic material is brought close to a magnet, the poles of the individual atoms of the material align along the magnetic field lines.If made permanent, this alignment can create a permanent magnet. Ferromagnetism only occurs in materials with partially filled electron shells. Ferromagnetism Free to share, print, make copies and changes.

7 Paramagnets act like magnets while in the presence of an externally applied magnetic field. Diamagnets create a magnetic field in opposition to an externally applied magnetic field.Thus, they repulse magnets. Diamagnetism is a property of all materials and always makes a weak contribution to the material's response to a magnetic field.However, for materials that show ferromagnetism or paramagnetism, the diamagnetic contribution becomes negligible.

8 Loops of wire in a magnetic field create current. Electromagnetism is the use of electric current to make magnets.Electromagnets are temporary magnets which keep their magnetic properties only when current is passing through them. Solenoids and electromagnets have many uses in physics and engineering because they allow the control of magnetic fields.

10 Key terms diamagnetism A weak form of magnetism that is only observed in the presence of an external magnetic field; due to an induced magnetic field in an opposite direction. dipole moment The vector product of the charge on either pole of a dipole and the distance separating them. electric charge A quantum number that determines the electromagnetic interactions of some subatomic particles; by convention, the electron has an electric charge of -1 and the proton +1, and quarks have fractional charge. electron shell The collective states of all electrons in an atom having the same principal quantum number (visualized as an orbit in which the electrons move). ferromagnetic Of a material, such as iron or nickel, that is easily magnetized. ferromagnetism The phenomenon whereby certain substances can become permanent magnets when subjected to a magnetic field. magnetic field A condition in the space around a magnet or electric current in which there is a detectable magnetic force, and where two magnetic poles are present. mass The quantity of matter which a body contains, irrespective of its bulk or volume.It is one of four fundamental properties of matter.It is measured in kilograms in the SI system of measurement. paramagnetism The tendency of magnetic dipoles to align with an external magnetic field; materials that exhibit this tendency become temporary magnets. spin A quantum angular momentum associated with subatomic particles; it also creates a magnetic moment.

14 Unmagnetized to Magnetized Iron (a) An unmagnetized piece of iron (or other ferromagnetic material) has randomly oriented domains.(b) When magnetized by an external field, the domains show greater alignment, and some grow at the expense of others.Individual atoms are aligned within domains; each atom acts like a tiny bar magnet.

17 Uses of Electromagnets An electromagnet induces regions of permanent magnetism on a floppy disk coated with a ferromagnetic material.The information stored here is digital (a region is either magnetic or not); in other applications, it can be analog (with a varying strength), such as on audiotapes.
