Graphene/Graphite Atmospheric Electricity Collectors - Plus Horrific Hexacopter Crash! Grades of Neodymium. This number represents the maximum energy product in Mega-Gauss Oersteds (MGOe) where 1MGOe (cgs units) equals 7958kJ/m3 (SI units).

The range available used to be N24 up to N52. The lower grades are no longer made and the range now starts at around N30 or N33. N50 is the highest readily available grade. N52 is possible but only in certain sizes. Although the maximum possible energy product is calculated in to be N64, it is unlikely such high strengths of Neodymium will be achievable in the near future (when the newest grades are commercially available they are often available only for direct sale into military applications). A suffix letter (or two letters) may then follow the number. The current range of Neodymium Iron Boron magnets is as follows:- However, the temperature rating for Neodymium is merely a guide value.

The total magnetic circuit that the Neodymium magnet is in determines its working point on the Intrinsic curve. Nomenclature of NdFeB grades. K&J Magnetics - Magnet Calculator. Click here to go to our Repelling Force Magnet Calculator that shows the repelling force generated between two same-sized magnets.

Most online calculators determine pull force based on a theoretical calculation of the flux density. With a few assumptions, flux density (in Gauss) can be related to the expected pull force. Unfortunately, this simplification often fails to match experimentally measured data. This page calculates expected pull forces based on extensive product testing. The Surface Field data is only valid for points along the center axis of the magnet, and assumes a single magnet in free space. All dimensions and distances must be in decimal format. This calculator only considers discs, cylinders and rings that are magnetized along the clyindrical axis. Convert MBH <—> kilowatt [kW] Common Unit Converters Length, mass, volume, area, temperature, pressure, energy, power, speed and other popular measurement unit converters.

Power In physics, power is the rate at which work is performed or energy is transferred. In the SI system, power is measured in watts (W). 1 watt is equal to 1 joule per second (J/s). Other units of power include ergs per second (erg/s), horsepower (hp), and foot-pounds per minute. Electric power is defined as the amount of work done by an electric current, or the rate at which electrical energy is transmitted. Unit definitions Using the Power Converter This online unit converter allows quick and accurate conversion between many units of measure, from one system to another. In this calculator, E notation is used to represent numbers that are too small or too large.

How to Calculate Kilowatt Hours (with Calculator) Edit Article Two Methods:Kilowatt Hours CalculatorCalculating Kilowatt Hours Most household appliances have a wattage label on the back or bottom.

This label lists the maximum amount of power the appliance can draw. But you probably don't operate every appliance in your home continuously, so if you're trying to estimate energy use over time kWh, or kilowatt hours, may be a more accurate measure. Kilowatt hours represent the estimated amount of energy an electrical appliance consumes in one hour, but can also be extended to estimate energy consumption over longer periods of time. Ad Steps.
