Summary of the article:
Magnetometers are widely used for measuring the Earth’s magnetic field, in geophysical surveys, to detect magnetic anomalies of various types, and to determine the dipole moment of magnetic materials.
Here are some key points about magnetometer sensors:
1. The magnetometer sensor in mobile phones reads the strength of the magnetic field around the device.
2. It measures the magnetic field along the X, Y, and Z axes and outputs the magnetic field as a 1-by-3 vector in microtesla (μT).
3. To check if your phone has a magnetometer, go to the “Sensors” section under “Features.” If it doesn’t mention a magnetometer or compass sensor, you probably don’t have one. However, you can still use a compass app that works via GPS.
4. The difference between a magnetometer and a metal detector is that magnetometers are used to find buried ferrous metals, while metal detectors refer to electromagnetic induction instruments.
5. iPhones do have a magnetometer sensor that measures fields within a ±2 gauss (200 microtesla) range and is sensitive to magnetic fields of less than 100 microgauss (0.01 microtesla).
6. The best location to place a magnetometer sensor is often on an edge or at a corner of the PCB (Printed Circuit Board). It should be placed away from other electromagnetic components like loudspeakers, vibrators, and NFC antennas.
7. Most cell phones come equipped with a magnetometer sensor for orientation sensing and basic apps like a compass app.
8. To use the magnetometer on your phone, you can download a compass app or use other applications that rely on magnetic field sensing.

What is a magnetometer sensor in mobile phones
The Magnetometer block reads the strength of the magnetic field around an Android™ device. The built-in magnetometer sensor on the Android device measures the magnetic field along the X, Y, and Z axes. The block outputs the magnetic field as a 1-by-3 vector in microtesla (μT).

How do I know if my phone has a magnetometer
Check the “Sensors” section under “Features”. If it doesn't mention a magnetometer or compass sensor you probably don't have one. If your device doesn't have a magnetometer, you still might be able to use a compass app which works via GPS – check for this in the app description.
What is the difference between a magnetometer and a metal detector
The term "metal detector" (MD) generally refers to some type of electromagnetic induction instrument, although traditional magnetometers are often used to find buried metal. The disadvantage of magnetometers is that they can be used only for locating ferrous metals.
Does iPhone have a magnetometer
The sensor is located towards the top right hand corner of the device, and measures fields within a ±2 gauss (200 microtesla) range, and is sensitive to magnetic fields of less than 100 microgauss (0.01 microtesla).
Where do you put a magnetometer sensor
The best locations are often to be found on an edge or at a corner of the PCB. Place any Hall effect sensor and its magnet as far away as possible from the magnetometer. Other electromagnetic components may include loudspeakers, vibrators, hearing aid coils, batteries and near field communication (NFC) antennas.
Do all cell phones have magnetometer
Smartphones come equipped with a magnetometer so that your phone can sense its orientation in space, and use basic apps like the Compass App to determine your location with respect to Magnetic North (or South!). The way this is done is through an internal chip that contains a 3-axis magnetometer.
How do I use the magnetometer on my phone
So click on the Play Store application. And search for a magnetometer Pro on the list click on the first item. Now you can read the description of the application. And discover some screenshots. Click
Do all smartphones have a magnetometer
Smartphones come equipped with a magnetometer so that your phone can sense its orientation in space, and use basic apps like the Compass App to determine your location with respect to Magnetic North (or South!). The way this is done is through an internal chip that contains a 3-axis magnetometer.
Can I use my phone as a magnetometer

Can a magnetometer detect guns
Local aberrations in the magnetic field produced by ferromagnetic objects, such as guns and knives, can be detected by extremely sensitive magnetometers.
Why does iPhone 13 have a magnetometer
When using an iPhone for directions, the phone considers not only the GPS sensor data, but also the magnetometer and accelerometers. That's part of how it can tell which direction you are pointed in. The magnetic field sensed by the internal compass is not actually pointing to the north pole.
Does my device have a magnetometer
Does your Android phone have a magnetometer Yup, chances are that it does as most Android devices do. Even if you have an old or a cheap phone, there's likely a magnetometer inside of it. And, there are a lot of apps out there that make use of that magnetometer to display a digital compass on your phone's screen.

Can mobile phones detect magnetic fields
The answer is Yes, sort of. Android smartphones come with a nifty sensor called a magnetometer, which is used to measure the strength and direction of magnetic fields.
Is a magnetometer still used today
A magnetometer is a passive instrument that measures changes in the Earth's magnetic field. In ocean exploration, it can be used to survey cultural heritage sites such as ship and aircraft wrecks and to characterize geological features on the seafloor.

The magnetometer finds ferrous metal targets used in landmines, Improvised Explosive Devices (IED), buried ordnance, other Munitions and Explosives of Concern (MEC), and hidden weapons.
What is magnetometer in iPhone used for
The magnetometer measures the strength of the magnetic field surrounding the device. In the absence of any strong local fields, these measurements will be of the ambient magnetic field of the Earth, allowing the device to determine its “heading” with respect to the geomagnetic North Pole and act as a digital compass.
