A gaussmeter measures the strength and direction of a magnetic field and can be used for scientific purposes or by paranormal researchers. There are two types: scalar and vector. The device is portable and easy to use, but multiple sources can create conflicting readings. Gaussmeters have various uses, including space exploration, geophysics, metal detection, and mobile phone technology.
A gaussmeter, also known as a magnetometer, is a device used to measure the strength and direction of a magnetic field. Small and portable versions are available and the user can take it with them to monitor magnetic fields while walking. The device may also be referred to as an electromagnetic field detector or EMF detector for short. The device has several scientific uses and is popular with paranormal researchers.
There are two types of gaussmeters: scalar and vector. The scalar gaussmeter measures the strength of the magnetic field in the area around the device. The vector gaussmeter measures the direction of the magnetic field depending on where the device is located and in which direction it is facing. A gaussmeter can combine both of these technologies.
Using a gaussmeter is a fairly simple process. The screen gives a readout of how strong the magnetic field is and can indicate the direction it’s coming from. If the person holding it gets closer to the magnetic source, the reading will increase; it will subside if the person moves away from the source. However, multiple sources can create conflicting readings and may require more advanced technology to determine where sources come from.
The changes in the magnetic field depend on where the user is and the strength of the earth’s magnetosphere in that particular area. The sun interacts differently with areas of the magnetosphere, and signal strength can vary with the sun’s activity. Some natural materials, such as rocks or specific rock formations, can also interfere with the gaussmeter reading.
Today, gaussmeters serve several uses. They are an invaluable tool in space exploration to learn more about the magnetism of foreign planets and other bodies in space. Here on Earth they can detect certain landscape formations and for this reason they are used in geophysics to get an idea of how the land is laid out. Some magnetometers can also detect hidden objects such as shipwrecks and are at work in metal detectors used both by beachcombers looking for lost items in the sand and by security teams to detect guns or other weapons.
Magnetometers are also gaining popularity in mobile phones. A phone using this technology can point directions to the user just like a compass does. It can also be used to allow the user to interact with the phone without actually touching it. While still in the early stages of development, a magnet can be used to interact with the phone’s magnetometer. The magnetometer can collect information about how the user is turning or moving their hand and then the phone responds to these movements.
