The Earth's organic magnetic forces are noticeably weak, measuring at 0.5 gauss and magnetic fields from family electronics can certainly exceed it, overpowering the compass needle. Publicity to strong magnets, or magnetic interference can often induce the magnetic poles of the compass needle to differ or maybe reverse. Avoid iron prosperous deposits when employing a compass, for instance, specified rocks which comprise magnetic minerals, like Magnetite. This is frequently indicated by a rock which has a surface which can be dim and has a metallic luster, not all magnetic mineral bearing rocks have this sign. To check out if a rock or an area is causing interference on the compass, get away from the region, and see When the needle on the compass moves.
