What is the potential magnetic field strength of Magnetars compared to the magnetic field of Earth?

Potentially a quadrillion times greater than Earth's field

Neutron stars generate magnetic fields far beyond anything encountered in everyday experience, often trillions of times stronger than Earth's field. A particularly extreme subset of these objects, known as magnetars, exhibit magnetic fields that are exceptionally intense. The magnetic strength in magnetars can reach levels calculated to be a quadrillion times greater than that of Earth. These extraordinarily powerful fields are so significant that they are theorized to warp the fabric of space-time around the object itself. These intense fields are responsible for channeling escaping charged particles, contributing to the intense energetic emissions observed from these compact objects.
