As widely known [22], the existence of the switching field distribution reduces the
squareness of the magnetic hysteresis loop, and thus it is necessary to prepare magnetic nanoparticles without anisotropy dispersion.
If you cannot determine approximate
squareness by eye, use a tapping guide.
A
squareness factor of 1 describes an ideal magnet material in which the magnetization of all domains is reversed in the same opposing field, the coercive field.
Generally, the various types of magnetization curves (with large or small
squareness ratio) can be obtained after annealing in longitudinal or transverse magnetic fields (O'Handley, 1999).
The Microgage 2D can measure straightness, flatness, parallelism,
squareness, and other geometric measurements to 0.001 inch over distances of 50 feet.
One-piece nut construction flanges provide built-in accuracy for concentricity,
squareness, and straightness.
A sheet length accuracy of 0.015 inches and a
squareness of 0.02 inches is maintained regardless of cutoff or line speed.
Overlay the 29-inch 2-by-6 cross-brace flush with the top and sides, check
squareness, and attach with four 2 1/2-inch deck screws per post.
Check the
squareness with a tape measure placed in opposite corners.
Marianne decided to break up the huge
squareness of the room with some unusual swirly paintwork, and trumped it all with a wonderfully escapist mural of a deserted seascape.
Commenting on the Grand Champion, he said: "It was a tremendous show heifer, full of meat, great style and
squareness, and clearly, all round, the best in show."
