Wireless Energy Transfer Through Magnetic Fields If the inventor Nikola Tesla (1856-1943) was always with us, he would surely be very satisfied, since he thought of transmitting energy wirelessly almost a century ago. In fact, his idea was not so impossible to implement, since energy can now be transmitted over the wire using magnetic fields, [...]
About Some Magnet Knowledge Permanent magnet material: The permanent magnet material is magnetized by an external magnetic field and does not disappear. It can provide a stable magnetic field to the external space. There are four common metrics for NdFeB permanent magnets: Remanence (Br) units are Tesla (T) and Gauss (Gs) 1Gs = 0.0001T A [...]
The magnetic field B is defined from the Lorentz Force Law, and specifically from the magnetic force on a moving charge: magnetic-force The implications of this expression include: The force is perpendicular to both the velocity v of the charge q and the magnetic field B. The magnitude of the force is F [...]
The strength of a magnet is indicated by either its pull force or its magnetic field strength. A magnet's strength is always stated in the product information for a magnet, however manufacturers use the following methods to discern this: Pull force The pull force of a magnet is the amount of force required to pull [...]
Magnetic fields - The strength of a magnetic field is measured in units of Gauss (G), or alternatively, in Tesla (T). In the MKS (metric) system of units, 1 T = 1 kilogram*ampere/second^2 = 10^4 G. magnetic field For comparison, the magnetic field of the earth at the surface is on the order [...]
“C”-shaped High Field Permanent Magnet Assemblies HS Magnetech recently announced the design and development of a 2+ Tesla Permanent Magnet Assembly for a Magnetic Research and Development application in the medical industry. We developed this “C” magnet technology to induce a high magnetic field into a defined area. The “C” magnet is one [...]
Permanent Magnet Assembly HS Magnetech has recently designed and developed a 2.2 Tesla Permanent Magnet Assembly for a Research and Development application in the medical industry. The design requirements for this application included a 5 mm sq. area that is 10 mm high with a magnetic field > 2 Tesla. We are currently [...]
