The gauss, symbol G (sometimes Gs), is a unit of measurement of magnetic induction, also known as magnetic flux density. Memorytamer 1 5 2 – automatic memory freeing app. The unit is part of the Gaussian system of units, which inherited it from the older CGS-EMU system. It was named after the German mathematician and physicist Carl Friedrich Gauss in 1936. One gauss is defined as one maxwell per square centimeter.

Sphere Magnets are ball shaped magnets widely used in consumer electronics, magic, hobby, consumer products, and R&D.These neodymium sphere magnets can be made as small as 1mm in diameter, or up to 2'. Our wide selection of sphere magnets in different colors and sizes give our customers many options for their applications.
As the cgs system has been superseded by the International System of Units (SI), the use of the gauss has been deprecated by the standards bodies, but is still regularly used in various subfields of science. The SI unit for magnetic flux density is the tesla (symbol T),[1] which corresponds to 10,000gauss.

Name, symbol, and metric prefixes[edit]
Albeit not a component of the International System of Units, the usage of the gauss generally follows the rules for SI units. Since the name is derived from a person's name, its symbol is the uppercase letter G. When the unit is spelled out, it is written in lowercase ('gauss'), unless it begins a sentence.[2]:147–148 The gauss may be combined with metric prefixes,[3]:128 such as in milligauss, mG (or mGs).
Unit conversions[edit]
Layouts lab 3 2 2 – templates for keynote themes. The gauss is the unit of magnetic flux density B in the system of Gaussian units and is equal to Mx/cm2 or g/Bi/s2, while the oersted is the unit of H-field. One tesla (T) corresponds to 104 gauss, and one ampere (A) per meter corresponds to 4π × 10−3 oersted.
The units for magnetic flux Φ, which is the integral of magnetic B-field over an area, are the weber (Wb) in the SI and the maxwell (Mx) in the CGS-Gaussian system. The conversion factor is 108, since flux is the integral of field over an area, area having the units of the square of distance, thus 104 (magnetic field conversion factor) times the square of 102 (linear distance conversion factor, i.e., centimetres per meter). 108 = 104 × (102)2.
Typical values[edit]

- 0.25–0.60 G – the Earth's magnetic field at its surface
- 25 G – the Earth's magnetic field in its core[4]
- 50 G – a typical refrigerator magnet
- 100 G – an ironmagnet
- 1500 G – within a sun spot[5]
- 10000 to 13000 G – remanence of a neodymium-iron-boron (NIB) magnet[6]
- 16000 to 22000 G – saturation of high permeability iron alloys used in transformers[7]
- 3000–70000 G – a medical magnetic resonance imaging machine
- 1012–1013 G – the surface of a neutron star[8]
- 4 × 1013 G – the quantum electrodynamic threshold

Each time you want to copy content from one application to another, side by side to compare files or work on several things at once in any other way, you need all windows are properly sorted. Magnet makes this process is clean and simple. With just a drag on the bank, you put any window on the left, right, top or bottom of your screen. And by dragging the corners sales to place them into quarters. Take advantage of these arrangements eliminates application be changing and greatly improves workplace efficiency.
Even a nice full screen side by side is a simple matter of drag to the top of the screen. If drag is not your thing, Magnet supports keyboard shortcuts for each command has to offer. We have a small icon in the menu bar where you can find pre-defined shortcuts or create those that fit your needs.
