English: Positions of North Magnetic Pole of the Earth. Poles shown are dip poles, defined as positions where the direction of the magnetic field is vertical. Red circles mark magnetic north pole positions as determined by direct observation, blue circles mark positions modelled using the GUFM model (1590–1890) and the IGRF-12 model (1900–2020) in 1 year increments. For the years 1890–1900, a smooth interpolation between the two models was performed. The modelled locations after 2015 are projections.
Українська: Північний магнітний полюс, що розташовується на Землі. Магнітне поле показує диполь, визначений позиціями де напрям магнітного поля вертикальний. Червоні кільця позначки північного магнітного поля визначені прямим спостереженням, голубі кільця позначки позиції змодельовані GUFM модель (1590-1890) та IGRF-12 (International Geomagnetic Reference Field Model) модель (1900-2020) з кроком в один рік. Для років 1890-1900, гладка інтерполяція виконана між двома моделями. Змодельовані місця після 2015 року є проекціями.
Русский: Географическое положение северного магнитного полюса Земли. Полюса, показанные на карте, подразумеваются полюсами магнитного диполя, и в точках их расположение наклонение магнитного поля вертикально. Красными кружками обозначены места, обнаруженные прямыми наблюдениями. Синие кружки - места, вычисленные по моделям «GUFM» (1590–1890) и «IGRF-12» (1900–2020) с временным шагом в 1 год. Для 1890–1900 годов, была осуществлена плавная интерполяция между двумя моделями. Смоделированные положения после 2015 года - предположительны.
