What do magnetometers indicate?

A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location.

What are magnetometers used for in space?

Spacecraft magnetometers are magnetometers used aboard spacecraft and satellites, mostly for scientific investigations, plus attitude sensing. Magnetometers are among the most widely used scientific instruments in exploratory and observation satellites.

Why do phones have magnetometers?

Magnetometers, sensors for measuring magnetic fields, have become ubiquitous in smartphones. These magnetometers are what enables the phone’s compass to func- tion. Several papers have also been pub- lished describing how such sensors could be used in education [8–11].

How deep can a magnetometer go?

In a general sense, the exploration depth of a magnetometer is unlimited. It is certainly sensitive to the Earth’s field and this is generated in the Earth’s Core, some 5000 km beneath our feet.

What kind of magnet picks up gold?

What Kind of Metals Are Magnetic? When these metals are combined with gold, it may make the piece (gold jewelry or gold bullion/nugget) magnetic. What metals are attracted to magnets? Cobalt, iron, nickel, neodymium, samarium, and gadolinium are all magnetic metals.

Is magnetometer same as compass?

The simplest, the magnetic compass, also simply known as a magnetometer, tracks the orientation of a magnetic needle within the Earth’s magnetic field, in the same way as a traditional compass.
