Earth magnetic field strength at surface
WebE = the RMS electric field strength in volts per meter, H = the RMS magnetic field strength in amperes per meter. The above equation yields units of W/m 2. In the USA the units of mW/cm 2, are more often used when making surveys. One mW/cm 2 is the same power density as 10 W/m 2. The following equation can be used to obtain these units … WebThe International System of Units (SI) unit of magnetic field intensity, strictly flux density, most commonly used in geomagnetism is the Tesla. At the Earth's surface the total intensity varies from 22,000 nanotesla (nT) …

WebJun 22, 2024 · As you are saying, the magnetic field strength for the Earth is at its surface (that is normally available without digging), that is the closest available connection between the Earth and the magnet/metal. ... The article's abstract: "Magnetic fields at the Earth’s surface represent only a fraction of the field inside the core 1. The strength ... WebA 1/4" cube (B444) has a Surface Field of 5754 Gauss. Using the Magnet Calculator, we can find the field at a specified distance. For Distance, enter a value equal to the length of one of our sides, in this case: 0.25". The Magnetic Field strength at that distance is 599 Gauss. Now, look at a big 1" cube, (BX0X0X0).
WebThat means the average density = M/V is 2/2^(3/2) = 1/sqrt(2) = 0.707 times that of Earth. Not a huge difference. That to me means a lot less iron. If you want a comparable magnetic field with a 40% larger radius, that probably implies a lot MORE iron in the core, so even less iron in the surface.
