Exact relationship between electric field and intensity ...

To answer the question why are the constants so often omitted, I would like to supplement QtizedQ's point (that the constants are of less interest because often relative intensity ratios are used).Focusing on proportionality rather than a strict equation with constants also leaves "amplitude" ambiguous, where it could refer to either the electric field or the magnetic field.

Measuring Magnetic Fields - nde-ed.org

Measuring Magnetic Fields. When performing a magnetic particle inspection, it is very important to be able to determine the direction and intensity of the magnetic field. As discussed previously, the direction of the magnetic field should be between 45 and 90 degrees to the longest dimension of the flaw for best detectability.

What is actually the B-H curve or magnetic hysteresis? - …

6/12/2017· B is the flux density of applied magnetic field. H is the field strength of the induced magnetic field within a material. So, the B-H curve shows the magnetic response of a material to an applied magnetic field/ flux. As the applied field/ flux is...

Magnetic field - Wikipedia

A magnetic field is a vector field that describes the magnetic influence of electric charges in relative motion and magnetized materials. A charge that is moving parallel to a current of other charges experiences a force perpendicular to its own velocity. The effects of magnetic fields are commonly seen in permanent magnets, which pull on magnetic materials (such as iron) and attract or repel ...

Magnetic field in the Arctic regions

Declination is actually the angle between the magnetic meridian and the geographic meridian (true north) at a given location. Declination can vary considerably along a magnetic meridian. Another common misconception is that the North Magnetic Pole is an "attractive" pole; that is, it attracts a compass needle towards it.

RP Photonics Encyclopedia - optical intensity, physics ...

In optical physics, the intensity I, e.g. of a laser beam at some location, is generally understood to the optical power per unit area, which is transmitted through an imagined surface perpendicular to the propagation direction. The units of the optical intensity (or light intensity) are W/m 2 or (more commonly) W/cm 2.The intensity is the product of photon energy and photon flux.

Earth's magnetic field - Wikipedia

Intensity. The intensity of the field is often measured in gauss (G), but is generally reported in nanoteslas (nT), with 1 G = 100,000 nT.A nanotesla is also referred to as a gamma (γ). The tesla is the SI unit of the magnetic field, The Earth's field ranges between approximately 25,000 and 65,000 nT (0.25–0.65 G). By comparison, a strong refrigerator magnet has a field of about 10,000,000 ...

Geomagnetism Frequently Asked Questions

These components may be measured in units of gauss but are generally reported in nanoTesla (1nT * 100,000 = 1 gauss). The Earth's magnetic field intensity is roughly between 25,000 - 65,000 nT (.25 - .65 gauss). Magnetic declination is the angle between magnetic north and true north.

Electric and Magnetic Field Intensity Analogy

The electric field lines denote the electric field intensity $vec{E}$ at every point so why doesn't magnetic field lines denote the magnetic field intensity $vec{H}$ at every point but the magnetic flux density $vec{B}$? I understand that basically it is the same thing and it actually the lines do denote $vec{H}$ as well because:
