Earth's magnetic dipole field lines and surface points P and E.
Earth's magnetic dipole field lines and surface points P and E.
Earth's magnetic field can be modeled as a magnetic dipole located near the center of the planet. Point \(P\) is located on Earth's surface near a magnetic pole, and Point \(E\) is located on the surface along the magnetic equator. Which of the following correctly compares the magnitude of the magnetic field at Point \(P\) (\(B_P\)) to that at Point \(E\) (\(B_E\)) and provides the correct justification?
