Humans have used the magnetic field of the Earth for navigation since the compass was invented in ancient China. Even the most powerful permanent magnet is not as strong as the strong electromagnets, so their applications are limited, but they still have very widely application,...
Magnetic properties of types construction materials - analyses of magnetic properties of steel of types gradePetr Keller
1,NdFeB magnet: it is the strongest magnet magnet, known as the magnetic king, has a very high magnetic properties of its maximum energy product over 10 times higher than ferrite. NdFeB mechanical processing performance is very good. Operating temperature up to 200 degrees Celsius. But also to...
Crystal - Magnetic Properties, Structure, Types: Electrons are perpetually rotating, and, since the electron has a charge, its spin produces a small magnetic moment. Magnetic moments are small magnets with north and south poles. The direction of the mome
or transverse, to the direction (along the rope) in which the wave is moving. An important family of transverse waves is generated by electromagnetic sources such as light orradio, in which the electric and magnetic fieldsconstitutingthe wave oscillate perpendicular to the direction ofpropagation. ...

Elliptical (track-shaped) permalloy(Ni19Fe81)dots, in which magnetic circular vortex and antivortex structures are stabilized, were prepared and the magnetic properties of perpendicular magnetization spots (turned-up magnetizations) at the cores of both types of vortices were studied. Using magnetic ...
Paramagnetic metals have a weaker attraction to magnets than ferromagnetic metals, and they don't retain their magnetic properties in the absence of a magnetic field. Paramagnetic metals include: •platinum •aluminum •tungsten •molybdenum ...
Some ceramics have special properties: some ceramics are magnetic materials; some are piezoelectric materials; and a few special ceramics are superconductors at very low temperatures. Ceramics and glasses have one major drawback: they are brittle....
Two types of composite Fe(Co)Ti(O x ,OH y ) nanoflakes were prepared using the mechanochemical synthesis. TEM, XRD, EDX, magnetisation and Mössbauer spectroscopy methods were applied for the characterisation of the as-synthesised and annealed samples. For the samples with Fe:Ti = 1:1 and...
