如何在Android中使用磁力计查找磁场强度

Question

I want to get Magnetic Field Strength from magnetometer of Android Device.

Using the magnetometer of android device I can get the data of magnetic field in the form of x,y & z axis in Micro Tesla.

But I don't know how to find magnetic field.

Any suggestion, Idea or Sample code are appreciated. . .

Answer 1

I am not sure if I am understanding your question.

Do you want the absolute value of the magnetic field instead of the components? It this is the case, it is enough to calculate the module (the square root of the sum of the squared values of every component).

The facto of having three components gives you more information: Not only the magnetic field but also the direction of it.
