Magnetic Separation Subjected

Magnetic field - Wikipedia

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents,: ch1 and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.: ch13 A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets.

Mineral processing - Wikipedia

Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is attracted to a magnet. In mines where wolframite was mixed with cassiterite, such as South Crofty and East Pool mine in Cornwall or with bismuth such as ...

The Hall Effect | Physics - Lumen Learning

The electric field caused by their separation opposes the magnetic force, F = qvB, and the electric force, F e = qE, eventually grows to equal it. That is, qE = qvB. or. E = vB. Note that the electric field E is uniform across the conductor because the magnetic field B is uniform, as is the conductor.
