{'magnetic equator': [0, 0, 1, 1], 'magnetic meridian': [2, 0, 1, 1], 'magnetic field': [0, 0, 0, 6], 'geographical pole': [0, 0, 0, 1], 'place earth': [0, 0, 0, 1], 'tropic': [2, 0, 2, 1], 'cancer': [2, 0, 0, 1]}
The point on Earth's surface where the planet's magnetic field is horizontal is known as the magnetic equator. It is the point where the magnetic field lines are parallel to the Earth's surface, and it is located slightly north of the geographic equator.
The location of the magnetic equator is not fixed and can vary with time. As of 2021, the magnetic equator is located roughly between 5 degrees north and 10 degrees north of the geographic equator, passing through regions such as Brazil, Uganda, and Indonesia.
It is important to note that the magnetic field is not perfectly horizontal at the magnetic equator but has a slight inclination. This is because the Earth's magnetic field is tilted at an angle to the planet's rotational axis.
