Does Metal affect a compass?
Iron, steel, and other magnets primarily influence a compass. But copper and aluminum can be used to damp oscillations of a compass because the magnet in the compass creates eddy currents in conductive but non-ferrous metals. In turn, the eddy currents create an opposing magnetic field and damp the swinging compass.
Is iPhone compass magnetic or true?
iPhone uses a built-in magnetic field sensor — a magnetometer — to give compass readings.
Is the compass on your phone accurate?
The short answer is yes. Magnetic variation (or declination) is something that can be corrected to true north in software. The magnetometer gives you the local magnetic field. If you don’t have interference, you can get magnetic north from that.
What makes a compass inaccurate?
Objects to avoid include wristwatches, keys, tables with metal legs or steel screws, mobile telephones and even heavy framed spectacles. Many geological formations, and for that matter, many rocks, are magnetized and can affect compass readings, as can electricity power lines.
What metal is used in compasses?
steel
Raw Materials The needle of a magnetic compass must be made of a metallic substance, which can be magnetized for an extended period of time. The most common substance used for compass needles is steel. Steel is an alloy of iron and a small amount of carbon.

Why are phone compasses bad?
Most Android devices contain a Magnetometer that is used by the internal compass. Any interference from a nearby magnetic source may affect the compass readings. If your device becomes unaligned due to the magnet then removing the source will help but you may need to restart your device.
Why does my Iphone compass not point north?
Head to Settings > Compass make sure that True North is enabled. If Compass doesn’t see your location, make sure you’ve turned on Location Services. Go to Settings > Privacy > Location Services, then turn on Location Services.
