If you want only the magnetic declination (variation) for a single day between 1900-present, visit our declination calculator. We hope that you find this NdFeB magnetic pull-force calculation tool to be helpful, and we plan to add more tools like it for other magnet materials in the future. Compute Earths Magnetic Field Values On-line calculators to estimate current and past values of the magnetic field. This calculator uses the World Magnetic Model as released in Dec 2019. As with any magnet-related engineering project, we recommend that you consult with a qualified magnetic design engineer for design path assistance. Resulting forces obtained by this calculator are only estimates meant to aid engineering professionals in early design stages of magnetic applications. A compass is only a magnetic needle inside a. The lines of force are generated by magnetic objects, such as the earth’s magnetic field or a bar magnet. The strength of the field is determined by the number of magnetic lines of force that pass through a given area. Magnet shapes that can be specified include Disc / Cylindrical and Square / Rectangular.īecause several additional variables exist in the real world that need to be accounted for to determine truly accurate magnetic pull forces in various scenarios, this calculator’s results should only be viewed as “first order” rather than used as the primary data for product realization. A magnetic field is an invisible force that can be detected using a compass. Calculations can be obtained for NdFeB magnet grades from 28MGOe (Br 10,400 Gauss) to 52MGOe (Br 14,400 Gauss). Properties that can be specified in the calculation include magnet size, shape, and material grade. This calculator allows engineers to estimate the attractive force (in lbf) of a Neodymium magnet in direct contact with a flat, sufficiently thick, steel work-piece. This new magnetic calculator can be found here: Neo Pull Force Calculator This magnetic force calculation utility can be used to help in estimating the attractive force of Neo magnets.
EARTH MAGNETIC FIELD CALCULATOR SERIES
Mathematically, the Earths magnetic field is normally described by a spherical harmonic expansion, a series of special. Nor can it be used to calculate the strength and direction of the magnetic field. To that end, we are pleased to announce the release of a pull force calculation tool for Neodymium Magnets. Although this simple description provides a way of conceptualizing the magnetic field it does not represent what really goes inside the Earth. In addition to providing a growing collection of informational articles related to magnetics in our TechTalk blog, we strive to make other beneficial magnet related resources available.
