Search for single magnetic charges in the largest of fields

Collisions between lead ions have produced the largest measured magnetic field in the Universe, enabling a search for elusive exotic particles that carry an isolated magnetic charge.

Break a magnet into smaller pieces, and each part will have its own north and south pole. But in the subatomic realm, an exotic particle called a magnetic monopole can possess an isolated magnetic charge — existing as only a north pole or a south pole. Writing in Nature, Acharya et al.¹ report the results of a search for these extraordinary particles using a very strong magnetic field.
