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 nT
AnswerMagnetic 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.

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 do you calculate magnetic flux density?
'Magnetic field strength' (symbol: H) is defined as 'the magnetomotive force, per unit length, of a magnetic circuit'. In SI, it is expressed in amperes per metre (A/m), which is often spoken as "'ampere turns' per metre".It's equation is: H = (IN) / lwhere:H = magnetic field strength (ampere per metre)I = current flowing through coil (amperes)N = number of turns in coill = length of magnetic circuit
What is magnetomotive force per unit length?
Magnetomotive force per unit length is the definition of magnetic field strength (symbol: H), formerly known as 'magnetising force'.Magnetomotive force is the product the the current flowing through a coil and the number of turns that make up that coil, and its SI unit of measurement is the ampere (although this is often spoken as 'ampere turn').So, the SI unit of measurement of magnetic field strength is the ampere per metre, although, again, it is often spoken as 'ampere turn per metre'.
What is the difference between the magnetic field of the Earth and the magnetic field of a bar magnet?

What is the unit of magnetic power?
That would be Gauss.
What are the properties of magnetic fields?
They always form a closed loop. They always start from the north pole and ends in the south pole. They never intersect each other. Magnetic lines of forces that are parallel to each other and are in the same direction repel each other.
What does the magnetic flux per unit area indicate?
the strength of a magnetic field
Unit of magnetism are?
The unit of magnetism are: Weber for magnetic flux, Tesla for magnetic flux density and ampere per meter for magnetic field strength.
What is the unit of the 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.
Why is the Gauss used instead of the Tesla to describe the strength of a magnetic field?
Both units are used to measure magnetic flux density. The tesla is the SI unit of measurement, whereas the gauss is an obsolete, cgsA, unit.
What is the si unit of magnetic field?
Oersted which is equal to 79.58 Am-1AnswerAn oersted is an obsolete (cgsA) unit of measurement for flux density, not magnetic field strength. The SI unit is the ampere per metre.
Is the strength of an electromagnet measured in volts?
That's a tricky question. Well, technically it is not measured in volts. The strength of an electromagnet depends on the electrical current which flows through its wires, but not on what drives that current. The current is measured in the amount of charge per unit time that flows through the wires. But when it comes to measuring the magnet, you have to refer to the magnetic field. Without it, there wouldn't be any "magnet." So, logically, to measure the strength of the magnet you must first measure the strength of the magnetic field. It's strength is measured in Volts per meter(V/m). So to measure the strength of the electromagnet you must measure the strength of the magnetic field whose formula is found in the next to last sentence. Hope this helps.
What is a gaussmeter?
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 unit of measurement is used to measure an electromagnetic field and what instrument is used to measure that?
An electromagnetic field has both electric and magnetic components. Units of Weber and Tesla are used to measure magnetic flux and magnetic flux density, while Volts measure electric fields.

How do you calculate the magnetic field strength in an injector cyclotron?
- Magnetic field strength is the intensity of a magnetic field at a given location. Historically, a distinction is made between magnetic field strength H, measured in ampere/meter, and magnetic flux density B, measured in tesla. Magnetic field strength is defined as the mechanical force (newton) on a wire of unit length (m) with unit electric current(A). The unit of the magnetic field, therefore, is newton/ (ampere x meter), which is called tesla. The magnetic field may be visualized by magnetic field lines. The field strength then corresponds to the density of the field lines. The total number of magnetic field lines penetrating an area is called magnetic flux. The unit of the magnetic flux is tesla x m2 = weber. The older units for the magnetic flux, maxwell = 10-8 weber, and for the magnetic flux density, gauss = maxwell / cm2 = 10-4 tesla, are not to be used any more. Magnetic flux density diminishes with increasing distance from a straight current-carrying wire or a straight line connecting a pair of magnetic poles around which the magnetic field is stable. At a given location in the vicinity of a current-carrying wire, the magnetic flux density is directly proportional to the current in amperes. If a ferromagnetic object such as a piece of iron is brought into a magnetic field, the "magnetic force" exerted on that object is directly proportional to the gradient of the magnetic field strength where the object is located. ------------------------------------------------------------------- B=μH Magnetic field in Solenoid B=μnI where n is turns/m So H=nI --------------------------------------------
What is a magnet's force called?
The strength of the magnet can be measured by the strength of flux density produce by its magnetic field in reference to a determine distance. This can be measured by the use of a Gauss Meter .

What is 40mT mean in magenetic fields?
40mT means 40 milli Tesla. A Tesla is a derived unit in the SI system of measures, and is a measure of magnetic field strength. The quantity given is rather small, but would be equal to that of a handful of fridge magnets. The Earth's magnetic field is about 30 micro Tesla.
