magnetic scan one of the tools abashed by exploration geophysicists in their investigation for mineral-bearing ore bodies or level oil-bearing sedimentary structures and by archaeologists to place and map the remains of buried structures.

What is iPhone magnetometer?

The magnetometer measures the confirm of the magnetic ground surrounding the device. In the want of any powerful local fields these measurements antipathy be of the ambient magnetic ground of the Earth allowing the artifice to determine its “heading” immediately notice to the geomagnetic North Pole and act as a digital compass.

How accurate is an iPhone magnetometer?

The iPhone 4S 5 and 5C hold right disparity components and the area readings are generally careful to +/-1 grade – meliorate sooner_than can be achieved immediately a transmitted hand-held Brunton or Silva compass.
