Unlike electricity, magnetic fields do not have charge. The positive pole is considered the North-seeking pole. To avoid such confusion and to standardize magnetic fields, measurement instrumentation as well as scientists and engineers use the terms ‘positive’ or ‘negative’ instead of ‘North’ or ‘South’. It’s easy to see why the confusion exists. The compass needle’s north is attracted to the magnetic South pole. This means that the actual North Pole, geographically, is a magnetic South Pole. When someone is talking about the North Pole, meaning the one to which the compass points north, they are actually referring to the North-seeking pole. The magnetic poles are not physically situated in the same place as the geographic poles. In fact, there are two types of poles on the Earth – magnetic and geographic. The concept is taken from the convention used to describe the Earth’s poles as North and South. Even so, polarity is occasionally mentioned in this industry, so we will mention it briefly. The topic of polarity has no scientific basis or proof in relation to PEMFs.
