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.
What else can I help you with?
What is the unit of magnetic power?
The unit of magnetic field strength or magnetic power is the tesla (T), named after the inventor Nikola Tesla. Alternatively, the gauss (G) is another unit commonly used for smaller magnetic fields, where 1 T equals 10,000 G.
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'.
Does the size of a magnet affect its strength?
Yes. Larger the magnet greater the magnetism. For example: Both the Sun and the Earth are powerful magnets. But the Sun's magnetism is 100 times greater than the magnetism of Earth. This is because the size of the Sun is also about 100 times greater than the Earth.Another AnswerThe intensity of a magnetic field is measured in terms of its flux density, which is defined as the flux per unit area. This corresponds to a weber per square metre('weber' is pronounced 'vay-ber') which, in SI, is given a special name: the tesla.So if a magnet has a given flux, then the smaller the area (perpendicular to the field) of that magnet, the higherits flux density. So the intensity of a magnetic field is a function of both the field (which depends on the type of material from which the magnet is made) itself and the perpendicular area of the magnet.

Do you measure temperature in Tesla?
No, temperature is typically measured in units such as Celsius (°C) or Fahrenheit (°F). Tesla is a unit used to measure magnetic flux density or magnetic field strength.
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.
What does the magnetic flux per unit area indicate?
The magnetic flux per unit area indicates how much magnetic field passes through a given area. It quantifies the strength of the magnetic field passing through a surface and is measured in units of teslas per square meter.
What unit of measurement is used to measure an electromagnetic field and what instrument is used to measure that?
The unit of measurement for electromagnetic fields is typically the tesla (T) or gauss (G), depending on the strength of the field. Instruments used to measure electromagnetic fields include gaussmeters and magnetometers.
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.
How do you measure the strength of a magnet?
The strength of a magnet is measured using a device called a gaussmeter, which detects the magnetic field produced by the magnet. The unit of measurement for magnetic strength is called gauss or tesla. The higher the gauss or tesla reading, the stronger the magnet.
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.
What is the magnetic field equation for a solenoid and how does it relate to the behavior of the magnetic field within the solenoid?
The magnetic field equation for a solenoid is given by B nI, where B is the magnetic field strength, is the permeability of free space, n is the number of turns per unit length, and I is the current flowing through the solenoid. This equation shows that the magnetic field strength inside a solenoid is directly proportional to the current flowing through it and the number of turns per unit length. As a result, increasing the current or the number of turns per unit length will increase the magnetic field strength within the solenoid.
What is the equation for calculation of susceptibility?
Susceptibility (χ) is a measure of how much a material will become magnetized in response to an applied magnetic field. The equation for magnetic susceptibility is given by χ = M/H, where M is the magnetization of the material (magnetic moment per unit volume) and H is the applied magnetic field strength. This relationship indicates how responsive a material is to the influence of the magnetic field.
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 unit describes the strength of a magnetic field?
The strength of a magnetic field is typically measured in units of tesla (T) or gauss (G). Tesla is the standard unit in the International System of Units (SI), while gauss is commonly used in certain applications.
Why is the Gauss used instead of the Tesla to describe the strength of a magnetic field?
The Gauss and Tesla are both units for measuring magnetic field strength. The Tesla is the SI unit, while the Gauss is a cgs unit. The Tesla is used in modern contexts due to its simplicity and alignment with the International System of Units.
