... Magnetic North: Think of the earth as a giant magnet (it is actually). The shape of the earth's magnetic field is roughly the same shape as the field of a bar magnet. However, the earth's magnetic field is inclined at about 11º from the axis of rotation of the earth, so this means that the earth's m ...

Field Surveys and Data Reductions
... archaeological features on known archaeological sites. More exceptionally, magnetometers are used for low-resolution exploratory surveys. Several types of magnetometer are used in terrestrial archaeology. Early surveys, beginning in the 1950s, were conducted with proton precession magnetometers. Dat ...

... 3. Why is a solenoid used to create a stronger magnetic field? What does it resemble? To increase the magnetic force from the presence of a current, without increasing the current (because that is often dangerous), you can wrap a wire into a coil. This is called a solenoid and it is MUCH safer. By ...
