What is a magnetometer?

Magnetometer is a scientific tool that measures magnetic fields. In addition to determining the magnetic field, the magnetometer can also determine its orientation and direction. Depending on the circumstances, there is a wide range of uses for magnetometers, along with several basic styles that can be used. Some of these devices are so sensitive that they are able to detect signs of increased Sun activity than these symptoms visible to the observatory. Geologists also use magnetometers to learn more about specific areas of the Earth's crust or to find magnetic minerals such as iron. These devices can also measure the impact of various human activities on the Earth's magnetic field. Several long -term scientific surveys maintain magnetometers continuously running for the purpose of collecting comparative data. Many ships also maintain a magnetometer on board to identify potential risks such as unmarked boats or shipwrecks that have been carried from their last time. Occasional archaeologists also useIt eats magnetometers in the form of metal detectors.

Study of the Earth's magnetic field can bring interesting information about Earth's development and universe in general. Scientists have documented clear changes in the Earth's magnetic field, some of which are actually recorded in a fossil recording in the form of iron particles that have re -evaluated in response to polarity switches. Magnetometers can also be used to look at the impact of solar activity on Earth, with scientists using data from the past to the graph and predict solar flares.

The complexity and size of these machines differ very much. Many of them are designed to work in the field, so they are at least reasonably portable. It is likely that you probably own a magnetometer because many people own their own compasses. The compass uses the Earth's magnetic fields to move directional needles that can be used to orientate a person using a compass. More delicate and more accurate magnetometers are UDrigided by numerous scientific institutions and universities.
