Can I cancel out gravity only with gyro and magnetometer?

On a device I want to detect a range of forces: small forces (Minimum around 0.01g) but also stronger forces like 0.1g - 0.15g. This device will have different positions in 3d space so in order to detect the small forces I have to know its angle in…
