Deviation of charged particle in uniform magnetic field ...

Suppose a charged particle enters perpendicular to the uniform magnetic field if the magnetic field extends to a distance 'x' which is less than or equal to radius of the path. In this case, r = m v q B. Angle of deviation 'θ' can be determined by using the formula. s i n θ = x r = x q B m v. θ = s i n − 1 ( x q B m v)

Magnetite - an overview | ScienceDirect Topics

Magnetite that is too coarse can become unstable and may lead to a collapse of the DM suspension in the cyclone, causing large losses of coal. Magnetite that is too fine is not normally unfavourable for operation, although finer magnetite is more difficult to recover in magnetic separators. The particle size distribution of the medium should be ...

Physical interpretation of hysteresis loops: Micromagnetic ...

E m is the magnetostatic energy produced by the magnetic particle itself. When E m is large enough this latter term can drive particles to seek a more demagnetized state resulting in complicated magnetization configurations. An example is the division of the magnetic particle into multiple regions of more or less uniform magnetization (magnetic ...
