Another function of the jig is to steady the piece of wood being cut to prevent excess cutting or inaccurate cuts. The size, shape, and function of a woodworking jig will vary significantly according to how it is being used and with what tool it is being used.
WMAP image of the (extremely tiny) anisotropies in the cosmic background radiation. Anisotropy /ËÃ¦naÉªËsÉtrÉpi/ is the property of being directionally dependent, which implies different properties in different directions, as opposed to isotropy.
Air Gap - The external distance from one pole of the magnet to the other though a non-magnetic material (usually air). Anisotropic - An anisotropic material has different properties in different directions. For example, wood which has a grain is stronger in some one direction than another. Like wood, neodymium magnets are also anisotropic. Even before it is magnetized, a neodymium magnet has a preferred magnetization direction.
