In a radial magnetic field
WebThe magnetic field produced by a steady current flowing in a very long straight wire encircles the wire. At a point P a radial distance r away from the wire it has magnitude B = μ 0 I/ (2πr). This equation is derived from one of Maxwell's equations called Ampere's law . WebWhat is meant by a radial magnetic field? It is a magnetic field which has the magnetic field lines along the radii of a sphere or a cylinder. It can be formed by having two unlike poles (north and south) of a magnet face each other. The north pole and the south poles are made to have surfaces which make the magnetic field Continue Reading 9

WebJan 13, 2024 · Mathematically you can surely see that $\vec{J}=0$ outside the wire and therefore the differential form of Ampere's law demands that $\nabla \times \vec{B} = 0$.. I guess what is confusing is that curl is often described in terms of "curling field lines", but that isn't entirely accurate - straight field lines can have a curl and curved field lines can … WebA uniform magnetic field is often used in making a “momentum analyzer,” or “momentum spectrometer,” for high-energy charged particles. ... A radial field gradient will also produce vertical forces on the particles. Suppose we have a field that is stronger nearer to the center of the orbit and weaker at the outside.
