What is the unit of magnetic field?
the unit of magnetic field is tesla (si unit ) and gauss (cgs ) unit.1 tesla = 10,000 gauss .1 tesla= 1N/mAAnswerIt depends on what you mean by 'magnetic field'. If you mean 'magnetic flux', then the SI unit is the weber(pronounced 'vay-ber'). If you mean 'magnetic flux density', then the SI unit is the tesla. If you mean 'magnetic field strength', then the SI unit is the ampere per metre.
How are magnetic field strengths measured?
We can say magnetic field strength is a measure of magnetic strength of a magnet.. like electric field density in electrostatics.... ex consider a current carrying wire which produce a magnetic field in radial direction... by using ampere law.. we can easily find magnetic field strength at a point (r distance from wire)... H=I/(2*3.14*r).. its like finding a electric field intensity by Guass law.......The magnetic field ranges from less than 30 micro-teslas (0.3 gauss) to 60 microteslas (0.6 gauss) The strength varies daily usually about 25 nanoteslas (nT) with variations every second of 1 nTAnswerMagnetic field strength (symbol H) is defined as the magnetomotive force per unit length of a magnetic circuit, and is expressed in amperes per metre (A/m). The original answer appears to be defining flux density(expressed in teslas), not magnetic field strength.
Why is the earths magnetic field unstable?
An excerpt from a paper by D.R. Fearn: The problem of magnetic field stability is complementary to the (much more widely studied) kinematic dynamo problem The dynamo mechanism converts the mechanical energy of convection into magnetic energy. If the field generated is unstable then the instability extracts energy from the field and might be expected to limit the strength of field attainable. This is an important consideration since the toroidal part of the field in the Earth's core is shielded from us by the insulating mantle and we do not know its strength. [Measurements of the DC electrical potential near the top of the mantle have been extrapolated downward to estimate the toroidal field at the core-mantle boundary (CMB), ...). This gives a toroidal field strength of a few gauss ( at the CMB), but with a weakly conducting mantle, a low value is to be expected and this result is not inconsistent with a strong toroidal field in the interior of the core (...)] There are good reasons for believing the toroidal field may be significantly stronger than the observed (poloidal) part of the field. If so, theoretical considerations may be the only way we have of determining the strength of the major component of the field. Linear theory (...) has shown that a broad class of fields, characteristic of the Earth's field, are unstable when their maximum strength exceeds a value of the order of 60 gauss which is a factor 10 greater than the observed poloidal field but is in line with many estimates of the hidden toroidal field. (...) To explain the observed features of the geomagnetic field, it is clearly important to understand how a magnetic instability evolves. Link below.
When the gauss law and coloumbs law are equal?
from anonymous surfer.... They are equal the only difference is that when the distance of the charge electrons are far so distant from each other, it is much better to apply Gauss's law while Coloumbs law for the other.....
How is Gauss Law used?
Gauss's Law is generally used to calculate the the total electric flux through any closed surface or the total charge that is enclosed by that surface. Realize that a closed surface is constructed. To find the flux across an open surface, you must construct a Gaussian surface to enclose the segment that is being analyzed. Hope that helped a little, Gauss is difficult bu practice will help alottt!!
What is magnetic field strength measured in?
Gauss
What does a Gauss Meter measure?
A Gauss Meter, or magnetometer, is an electronic device that is used to measure the strength of magnetic fields. Gauss Meters are commonly used to measure the strength of magnets and magnetic effects in electronics. They can also be used as metal detectors.
What is 2825 gauss?
Gauss is an old (cgs) unit for magnetic field strength. To convert to modern units (tesla), divide by 10,000.
How strong is earths magnetic field?
Magnetic Field Strengths are often measured in the unit "gauss" ( the SI unit is the "tesla"). The strength of the Earth's Magnetic Field, measured at its core, is 25 gauss. More useful probably is the strength of the field at the surface of the Earth. This varies from place to place. Also, it seems to have become weaker over recent centuries. The strength at the surface is about 0.3 to 0.6 gauss. (For comparison, a typical fridge magnet is about 50 gauss.)
What does magnetic flux mean in physics?
The magnetic flux is the measure of the strength of a magnetic field. The total magnetic flux through a closed surface is zero, according to Gauss's law for magnetism.
How strong is earth's magnetic field?
Not very strong in comparison with a typical small "bar magnet" which has a field strength of roughly 100 gauss. Earth's magnetic field strength at the surface is about 0.3 to 0.6 gauss. That's stronger than some planets and weaker than others.
How many gauss in a volt?
There are no Gauss in a volt. The Gauss is the centimetre-gram-second system unit of measurement of a magnetic field (which is also known as the "magnetic flux density", or the "magnetic induction"). It was named after the German mathematician and physicist Karl Gauss. One gauss is defined as one maxwell per square centimeter; it equals 1 × 10−4 tesla. - - 10−9-10−8 gauss in the magnetic field of the human brain - - 0.31-0.58 gauss: in Earth's magnetic field - - 50 gauss: in a typical refrigerator magnet - - 100 gauss in a small iron magnet - - 2000 gauss in a small neodymium-iron-boron magnet - - 15,000-30,000 gauss in a medical magnetic resonance imaging electromagnet
