A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (or flea) immersed in a liquid to spin very quickly, thus stirring it. The rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel with the liquid.
Sheet aluminium is spun or stamped into form. Due to the softness of the metal, it may be alloyed with magnesium, copper, or bronze to increase its strength. Sheet aluminium is commonly used for baking sheets, pie plates, and cake or muffin pans. Deep or shallow pots may be formed from sheet aluminium.
In electromagnetism, the magnetic susceptibility (from Latin susceptibilis 'receptive'; denoted χ, chi) is a measure of how much a material will become magnetized in an applied magnetic field. It is the ratio of magnetization M ( magnetic moment per unit volume ) to the applied magnetic field intensity H .
The 300 series is non-magnetic. 302 is a Chromium-Nickel austenitic alloy used for blenders and mixers. 303 is an austenitic stainless steel specifically designed to exhibit improved machinability. 303 SE is austenitic chromium-nickel steel to which selenium has been added to improve machinability and non-galling characteristics.

An electric blender. A blender (sometimes called a mixer or liquidiser in British English) is a kitchen and laboratory appliance used to mix, crush, purée or emulsify food and other substances. A stationary blender consists of a blender container with a rotating metal or plastic blade at the bottom, powered by an electric motor that is in the ...
Recycling centres use magnetic separation often to separate components from recycling, isolate metals, and purify ores. [1] Overhead magnets, magnetic pulleys, and the magnetic drums were the methods used in the recycling industry. [1] Magnetic separation is also useful in mining iron as it is attracted to a magnet.

Seen in some magnetic materials, saturation is the state reached when an increase in applied external magnetic field H cannot increase the magnetization of the material further, so the total magnetic flux density B more or less levels off. (Though, magnetization continues to increase very slowly with the field due to paramagnetism.)
A "horseshoe magnet" made of Alnico 5, about 1 inch high.The metal bar (bottom) is a keeper. A magnet keeper, also known historically as an armature, is a bar made from magnetically soft iron or steel, which is placed across the poles of a permanent magnet to help preserve the strength of the magnet by completing the magnetic circuit; it is important for magnets that have low magnetic ...
