How do helmholtz coils work
WebDec 25, 2015 · Be reminded that this is just an evaluation of the magnetic flux density along the central symmetry line of a coil pair. If you are interested in the full 2D field, things become more complicated. But this simple evaluation gives you some idea what happens when you move the two coils apart. For a longer homogeneous field you need more coils. WebA Helmholtz coil consists of two circular coils of radius with a common axis placed symmetrically in parallel planes at and separated by the distance Both coils carry …

A Helmholtz coil is a device for producing a region of nearly uniform magnetic field, named after the German physicist Hermann von Helmholtz. It consists of two electromagnets on the same axis, carrying an equal electric current in the same direction. Besides creating magnetic fields, Helmholtz coils are … See more The calculation of the exact magnetic field at any point in space is mathematically complex and involves the study of Bessel functions. Things are simpler along the axis of the coil-pair, and it is convenient to think about the See more To improve the uniformity of the field in the space inside the coils, additional coils can be added around the outside. James Clerk Maxwell showed in 1873 that a third larger-diameter coil … See more • On-Axis Field of an Ideal Helmholtz Coil • Axial field of a real Helmholtz coil pair • Helmholtz-Coil Fields by Franz Kraft, The Wolfram Demonstrations Project See more Most Helmholtz coils use DC (direct) current to produce a static magnetic field.
