Earth's magnetic field always has a horizontal component except at ______.

Understand the Problem

The question is asking at which location on Earth the magnetic field does not have a horizontal component. It presents four options related to magnetic phenomena.

More Information

At the magnetic poles, the Earth's magnetic field becomes vertical, resulting in no horizontal component. This is due to the angle of dip being 90 degrees at these poles.

Tips

A common mistake is confusing the geographic poles with the magnetic poles. Only the magnetic poles have a vertical magnetic field, eliminating the horizontal component.
