A magnet is a material that can exert a noticeable force on other materials without actually contacting them. This force is known as a magnetic force and may either attract or repel. While all known materials exert some sort of magnetic force, it is so small in most materials that it is not readily noticeable.
Guide to Metal Detection LOMA SYSTEMS ® offers this guide to metal detection to assist food and packaging companies in establishing an effective metal detection program that meets regulatory guidelines. How a Metal Detector Works. The most widely-used type of metal detector in the food industry functions on the principle known as the 'balanced coil' system.

In addition to visible light, aluminum pigments reflect infrared and ultraviolet lightwaves. Aluminum Powder 101 Production of aluminum powder. Aluminum powder was originally produced by using a stamp mill to create flakes. In the 1920s, E. J. Hall pioneered the process of spraying molten aluminum to make powder droplets.
The magnetic moment of a system measures the strength and the direction of its magnetism. The term itself usually refers to the magnetic dipole moment. Anything that is magnetic, like a bar magnet or a loop of electric current, has a magnetic moment. A magnetic moment is a vector quantity, with a magnitude and a direction.
Magnetic particle Inspection (MPI) is a non-destructive testing (NDT) process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization.
Magnetic particle examination (MT) is a very popular, low-cost method to perform nondestructive examination (NDE) of ferromagnetic material. Ferromagnetic is defined in ASME Section V as "a term applied to materials that can be magnetized or strongly attracted by a magnetic field."
1.1 Process and Features of Powder Metallurgy Powder metallurgy (P/M) is a materials processing technology to create new materials and parts by diffusing different metal powders as raw ingredients through the sintering process. Products are created by P/M using the basic process shown in Figure 1.
Aluminium(British English), or (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. It is a silvery-white, soft, non-magnetic and ductile metal in the boron group.By mass, aluminium makes up about 8% of the Earth's crust, where it is the third most abundant element (after oxygen and silicon) and also the most abundant metal.
ASTM's electrical and magnetic conductor standards are instrumental in specifying, evaluating, and testing the electrical, magnetic, and physical properties of conducting materials used primarily in electrical and magnetic devices and related equipments.

Plating to make aluminum magnetic 2006. Q. I need to obtain a magnetic coating on aluminum. That coating has to be radio-opaque. I have heard of gold plating aluminum using a nickel substrate. That is a magnetic material. I want to know how I can obtain a magnetic coating on aluminum (What technique I have to imply?) Thanks, Andrea Jaimes

ALUMINIUM ALLOYS. The process where the aluminium is shaped to its required form. This process is used for making the vast majority of aluminium products from spectacle frames, telephone bodies, aeroplane fuselages or spaceship bodies. The malleability of aluminium means .
Specialized magnetic shielding materials usually have a higher relative permeability, but a lower saturation point. Permeability is the degree of magnetization of a material that responds linearly to an applied magnetic field. For shielding, Relative Permeability is the Permeability divided by the Permeability of free space, a constant.
