The measurement of a magnetic field it was seen as something extremely complicated, it was also only a matter reserved for the area of ​​pure sciences. Measurements of a magnetic field are obtained with certain sensors and can now be on mobile phones.

Detecting a magnetic field and having a measurement of it is easy, doing it only involves the use of certain ones applications on the smartphone you own. If you want to learn how to detect a magnetic field and measure it, read on.



How can I detect a magnetic field with my mobile phone?

Mobile phones include more and more sensors in their configuration, the hardware of a mobile phone now has sensors such as proximity, temperature, and even the sensor that is used for the use of GPS.

Similarly, smartphones have a gyroscope, which is used to display video and audiovisual material in full screen, and has other functions. But today we will talk about the detection of the magnetic field and its measurement.

As the years go by, technology advances and cell phones, along with the rest of electronic devices, include more and more configurations and sensors for various functions, including sensing a magnetic field.

There are apps that allow Android users to measure the magnetic field they want, but they have some limitations. And is that like the use of the flash, downloading a flashlight, it is necessary that the mobile has a focus or light in its hardware.

Applications like Ultimate EMF Detector Free, Ghost EMF Detector, EMF Detector and others, they only work if the phone has the right sensor: one that can detect magnetic fields. Otherwise, a magnetic field cannot be detected with the mobile phone.

The best apps to measure electromagnetic and magnetic fields

Applications like Ultimate EMF Detector Free, Ghost EMF Detector, EMF Detector and others, they only work if the phone has the right sensor: one that can detect magnetic fields. Otherwise, a magnetic field cannot be detected with the mobile phone.

In the event that a magnetic field is not detected with any of these applications, al time of installation the measurement will be 0 , as the sensor making these measurements is not inside the device.

But if you have this sensor then the measurement will be greater than 0 at any time, even if it is far from a magnetic field, because at least it should show values ​​close to it.

And basically what you need to do to measure a magnetic field with your mobile is download one of those applications on Google Play . If you have a Chinese brand phone, which generally does not have this service, you can choose to download and install it in another way.

To prove that your mobile serves as a magnetic field meter, then you need to create one, and it is also convenient to have a conventional meter of these, in so you can compare the measurements.

Usually, any software of this type has measurements in microtesla and gauss units. You can set it up on the drive that's right for you.


And from there start using it as a meter, creating magnetic fields as you want, or even in the places of your home where the direct current passes ; You will see how the values ​​change depending on the magnitude of the magnetic field it presents.



What can be measured with the sensors of a mobile phone?

Electromagnetic fields

light intensity

Atmospheric pressure

Movement speed

What other similar measurements can be made with a mobile phone?

They are really very varied and, as was said before, they depend on the number of sensors a mobile phone has in its hardware. Also, the newer models of cell phones that are used in this type of thing, the more sensors they will have , including, for example, the sensor of the metal detector.

The variety of sensors a smartphone can have now is impressive, and it is that with them you can do great things and within reach of the device that is normally used the most.


To see which other sensors you can use with your mobile, we recommend that you download DevCheck Hardware and System Info. With this tool you will be able to see which are all the sensors that your hardware has available, and thus start using them for different purposes.

You can then realize that your phone is on degree of amazing functions. For example, you can measure ambient noise or atmospheric pressure.

You can also get to know the Altitude above sea level and the speed at which you move, plus other amazing features.
