Australian Geomagnetic Reference Field Values

If the chosen location is outside the coloured area in the adjacent image then a global magnetic field model will be used for the calculations.

Magnets and Electromagnets - HyperPhysics Concepts

The magnetic field lines of a bar magnet can be traced out with the use of a compass. The needle of a compass is itself a permanent magnet and the north indicator of the compass is a magnetic north pole.

Visualizing magnetic fields - Cool Experiments with Magnets

Visualizing magnetic fields. How can I visualize the magnetic field? At first, this seems like an impossible task since you can not see magnetic fields.

Magnetosphere - Wikipedia

Study of Earth's magnetosphere began in 1600, when William Gilbert discovered that the magnetic field on the surface of Earth resembled that on a terrella, a small, magnetized sphere.

Arduino: measuring the Earth's magnetic field with the ...

The HMC5883L magnetometer. This component (a small chip) HMC5883L, produced by Honeywell, bases its operation on AMR (Anisotropic Magnetoresistive) technology and allows you to be able to measure both the direction and the magnitude of the earth's magnetic field.

Notes about Electromagnetic Pulse - EMP-

The magnetic field strengths are the total magnetic field strengths in nanoteslas. The angle shown in parenthesis is angle of the magnetic field downward direction. The influence of the downward tilt on the fast E1 pulse is quite complicated, but when there is less downward tilt, the intensity of the EMP tends to be more symmetrical around the detonation point.

Geomagnetic field | geophysics |

Geomagnetic field: Geomagnetic field, magnetic field associated with the Earth. It primarily is dipolar (i.e., it has two poles, these being the north and south magnetic poles) on the Earth's surface.

How Magnets Work - Official Site

How is a magnetic field created? When current flows in a wire, a magnetic field is created around the wire. From this it has been inferred that magnetic fields are produced by the motion of electrical charges.

Earth's magnetic field - Wikipedia

Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from the Earth's interior out into space, where it meets the solar wind, a stream of charged particles emanating from the Sun.

A gallery of magnetic fields -

A gallery of magnetic fields. This page has several cool diagrams of magnetic fields. Studying these help give you a feel for how magnets actually interact with one another and with other objects.

Magnetic field - Georgia State University

Magnetic Field Units. The standard SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law F magnetic = qvB to be composed of (Newton x second)/(Coulomb x meter).

What are magnetic fields? (article) | Khan Academy

A compass is nothing more than a tiny magnet suspended such that it can freely rotate in response to a magnetic field. Like all magnets, a compass needle has a north pole and a south pole that are attracted and repelled by the poles of other magnets.
