This page lists examples of magnetic induction B in teslas and gauss produced by various sources, grouped by orders of magnitude. The magnetic flux density does not measure how strong a magnetic field is, but only how strong the magnetic flux is in a given point or at a given distance (usually right above the magnet's surface).
The tesla (symbol: T) is the unit of magnetic flux density (also called magnetic B-field strength) in the International System of Units (SI). One tesla is equal to one weber per square metre .
The gauss is the unit of magnetic flux density B in the system of Gaussian units and is equal to Mx/cm 2 or g/Bi/s 2, while the oersted is the unit of H-field. One tesla (T) corresponds to 10 4 gauss, and one ampere (A) per metre corresponds to 4π × 10 −3 oersted .
The strength of a magnetic field is measured in units of tesla in the SI units, and in gauss in the cgs system of units. 10,000 gauss are equal to one tesla. [1] Measurements of the Earth's magnetic field are often quoted in units of nanotesla (nT), also called a gamma. [2]

The lowest-degree Gauss coefficient, g 0 0, gives the contribution of an isolated magnetic charge, so it is zero. The next three coefficients – g 1 0, g 1 1, and h 1 1 – determine the direction and magnitude of the dipole contribution. The best fitting dipole is tilted at an angle of about 10° with respect to the rotational axis, as ...
Liquid helium is used as a coolant for many superconductive windings. It has a boiling point of 4.2 K, far below the critical temperature of most winding materials. The magnet and coolant are contained in a thermally insulated container called a cryostat.
World Health Organization chief Tedros Adhanom Ghebreyesus has been released from Rio de Janeiro's Hospital Samaritano Barra da Tijuca after spending the night under observation, the hospital said.
