Two magnets that attract or repel each other have which type of energy store?

The correct answer is magnetic energy store. When two magnets interact with each other, they either attract or repel based on their magnetic fields. This interaction is a manifestation of the magnetic force, which arises from the arrangement of electrons within the materials of the magnets. The energy associated with this magnetic interaction is stored in the magnetic field created by the magnets.

Magnetic energy is a fundamental concept in physics that explains how magnets work and how they can exert forces over distances without physical contact. In contrast, nuclear energy is related to the forces within an atomic nucleus, elastic energy pertains to stretched or compressed materials like springs, and chemical energy is found in the bonds between atoms in molecules. Since the question specifically addresses the forces between magnets, the magnetic energy store is the appropriate and relevant choice.
