The central theme of Stefan Mayer’s art is the uncertain or often missing visual access; essential features and spatial elements remain vague or completely invisible. Through magnetic field interferences, thermodynamic interventions, and random circuits, visual gaps and voids are created. His works range from subtle outdoor interventions to expansive installations in museums and galleries. His current projects primarily occur in conditional locations, public spaces, and urban contexts. These inconspicuous local interventions alter the quality of local connections between points or objects, as well as spatial structures like the global geomagnetic field, both in function and effect.

„The Invisible as Material“ This lecture traces a path from conceptual art of the 1960s through empirical research in art education, to an ongoing sculptural practice working with invisible physical forces: thermal change and, above all, the Earth’s magnetic field as primary material.

… in progress. More information coming soon.

OVERVIEW:
The following examples provide a brief overview of the development of invisible materials, the structuring of spaces through magnetic fields, random circuits, gas columns, and changes in thermal conditions. Each image is a link to detailed pages.

Book: Campos Magnéticos – Magnetfelder 1992-2023

„Invisible art, woven from magnetic fields, challenges the senses of human perception and is a vast new area of contemporary art to be explored. In „Magnetic Fields – Magnetfelder – 1992-2023″, the latest release from Lestu (2024), Stefan Mayer brings together a collection of critical analyses of his work. Professors, journalists and artists come together to produce a fascinating exploration of this concept. Available to read and download from the publisher’s bookshop, the book invites readers to dive into this invisible universe and discover the multiple layers of meaning and perception it offers.“ Kelma Cunha Gallas – Chief Editor (Text).

Random Field

two electromagnets aligned in the site-specific inclination and declination generate a local reversal of the earth’s magnetic field
Vertical Field Double

In the workshop for the repair of large clocks, the installation intervenes in the natural order of the earth’s magnetic field.
Vertical Magnetic Field – Balkans

A mobile eletromagenet is powered by a 12V battery. It creates an intervention in the local earth magnetic field in many places of the former Eastern Bloc and neighboring countries. It changes the north-south structure into a vertical alignment 2021
Vertical Magnetic Field – Munich

The electromagnet relativizes the north-south structure of the earth’s magnetic field, changing it locally into the one relating top and bottom.
Asphalt Rundown

Salt water flows down asphalt, hits a contact and creates an electric circuit – or not. Rome, Italy 2016
Gas Clouds and Gas Columns

Random Circuits

Connections of urban objects made of copper wire, a lithium battery and a clamp. Random circuits generated by simple units. Used in an urban or rural context, all wire work or multipolar layouts have an uncertain quality: it always remains open whether the circuit closes at random. 2016-2020
Magnetic Fields

In the gallery space, minimal cubic magnetic elements generate local changes in the earth’s magnetic field of different characteristics and orientation (2006 Bayreuth)
