Magnetism

Magnetism is a class of physical phenomena that are mediated by magnetic fields, which are forces that attract or repel certain materials. It is related to electricity, and the combination of the two is known as electromagnetism.

Magnetic materials

Certain metals are attracted to magnetic forces, and magnetic forces can also repel other magnetized objects.

Lodestone is a type of naturally occurring magnetic iron mineral composed of magnetized magnetite.

Alchemy

Alchemically strengthened lodestones can be embedded into lodestone boots designed to aid in rope climbing. The magnetic forces of the lodestones, one embedded into each boot, help keep the grip of their wearer's feet around a rope, and can also adhere the boots to magnetically reactive surfaces.

Lodestone arrows employ a reaction between iron and an alchemical resin to briefly magnetize their arrowheads. When fired, such an arrow veers more accurately toward a target made of or wearing metal. The effect wears off within seconds, however.

Other uses

Magnetic items can also be used by those skilled in tracking spirits to indicate their presence and movements.

In magic

Magnetic devices are sometimes used in magic, such as the Material Failsafe ritual developed by Grand Lodge arcanists of the Pathfinder Society to contain extraplanar anomalies of the Maze of the Open Road, which uses a lodestone as a focus item.

In traps

Some traps employ an electric charge to a lodestone to activate a powerful magnetic field that can open or close doors and pull nearby metal objects, such as armor and weapons, toward it.

On Golarion

On Golarion, magnetically reactive metals include iron, adamantine, and dawnsilver. Magnetic forces can also repel nanites, such as those that plague technologically dense parts of Numeria.

Gregorias Desmaske, a former professor of natural sciences at the University of Lepidstadt, claimed to employ Stasian technology, magnetite, and moonstone to generate lunar magnetism, an artificial recreation of tidal forces believed to be associated with werecreatures and capable of blocking a werecreature's transformation between forms.

Magnetite golems are golems made of magnetized magnetite.

As of 4719 AR, the gargoyle Paravaax of the Mwangi Expanse was composed of solid lodestone, and while hibernating he generated a magnetic field powerful enough to interfere with compasses within a significant area.

In the Great Beyond

Living lodestones are elemental beings that emit powerful a magnetic field.

Zuhra shuyookhs of the Plane of Metal are both charismatically and literally magnetic.

Spiny lodestones are magical spellhearts of magnetite that can generate magnetically powered forces of acceleration.
