Real Levitation

leave a comment »

There are 3 basic schemes for using electromagnetic fields/diamagnetic for real levitation (no energy input is required and the levitation can last forever):

  • Superconducting levitation
  • Diamagnetic levitation
  • Diamagnetically stabilized levitation

These are explained at the educational pages of the High Field Magnetic Laboratory, Holland.
Favourite example: the levitating frog

Sky Ear
Usman Haque, 2004

[From website: Sky Ear had its last full-scale public launch on September 15, 2004 at Greenwich Park, London. There are currently no confirmed flights planned for the future, though various discussions continue.

Electromagnetic fields (EMF) exist just about everywhere in our atmosphere. Urban locations in particular have a diverse and vibrant hertzian culture, with mobile phone calls overlapping text messages, combining television broadcasts with garage door openers that interfere with radio transmissions and wireless laptops, etc., not to mention the natural EMF that already exists in the atmosphere. This project is a spatial investigation of some of these phenomena.

Sky Ear is a non-rigid carbon-fibre “cloud”, embedded with one thousand glowing helium balloons and several dozen mobile phones. The balloons contain miniature sensor circuits that respond to electromagnetic fields, particularly those of mobile phones. When activated, the sensor circuits co-ordinate to cause ultra-bright coloured LEDs to illuminate. The 30m cloud glows and flickers brightly as it floats across the sky.

As people using phones at ground-level call into the cloud (flying up to 100m above them) they are able to listen to distant natural electromagnetic sounds of the sky (including whistlers and spherics). Their mobile phone calls change the local hertzian topography; these disturbances in the electromagnetic fields inside the cloud alter the glow patterns of that part of the balloon cloud. Feedback within the sensor network creates ripples of light reminiscent of rumbling thunder and flashes of lightning.

Sky Ear shows both how a natural invisible electromagnetism pervades our environment and also how our mobile phone calls and text messages delicately affect the new and existing electromagnetic fields.]

Haunting

leave a comment »

Haunt
A collaboration between Usman Haque and Professor Chris French (Goldsmiths College Psychology Department), 2005.

[From website: Using humidity, temperatures and electromagnetic and sonic frequencies that parapsychologists have associated with haunted spaces, this project aims at building an environment that feels “haunted”: a non-visual architecture. A circular featureless chamber was built inside a standard row house apartment in North London, measuring approximately 3m x 3m, and 4m high. The temperature was approximately 18 degrees celcius and the light level was about 1 lux. A purpose built infrasound cabinet and two electromagnetic coils provided varying stimuli.

The objective of the experiment was to determine whether infrasonic frequencies and magnetic field fluctuations similar to those found in supposedly “haunted” spaces can elicit physiological or psychological effects similar to those experienced in “hauntings”. During participation galvanic skin response of the participants was measured and they were required to note down any unusual phenomena they experienced, marking where these occured on a map of the room, and at what time. Each session lasted approximately 50 minutes. Participants were randomly placed in one of 4 groups though they were not informed of their group until the end of the experiment: those subjected to infrasound, those subjected to magnetic fields, those subjected to both and those subjected to neither. The objective of the experiment was to determine whether infrasonic frequencies and magnetic field fluctuations similar to those found in supposedly “haunted” spaces can elicit physiological or psychological effects similar to those experienced in “hauntings”.

Ferrofluid Sculptures
Sachiko Kodama

sculpture

[from the website: Ferrofluid is a very interesting material originally developed by NASA it has now found itself been used for a whole range of devices including dampers for controlling and stabilizing large building that move around in the wind. Whats also amazing is that they have such lovely visual qualities when magnetized. The term liquid architecture is used a lot in interactive architecture based on the ideas of how architecture becomes animated by adding the 4th Dimension of Time. Sachiko has taken this idea of liquid architecture more literally with these stunning sculpture made from Ferrofluid which changes its state by the introduction of electro-magnetic waves into the fluid turning it solid.]

Energy Fluxion Band

Gregory Shakar in collaboration with Brendan Fitzgerald

fluxion band

[From website: Sensing invisible energy.
The Energy Fluxion Band is a wearable device that displays the level of electromagnetic (EM) energy in the wearer’s immediate environment. It detects energetic radiations from an endless array of technological sources including cell phones, computers, radio transmitters and power lines. The project is meant to enhance the user’s awareness of the electromagnetic landscape that is produced by the generation, distribution and consumption of electrical energy. This terrain pervades our lives, but typically goes unnoticed.

The Energy Fluxion Band’s LED bar-graph display recalls the familiar form of audio volume indicators whose lights pulse in rhythm with incoming sounds levels. Similarly, the Energy Fluxion Band’s display fluctuates in concert with the changing amplitudes of EM signals that impinge upon it from moment to moment. For example, when the wearer switches on a microwave oven – a strong EM source – the Fluxion Band illuminates most of its LEDs and glows brightly in response to the intense emission. When the wearer makes a call on their mobile phone, the bar-graph beats rhythmically as the phone exchanges packets of wireless data with a cellular transceiver.

The Energy Fluxion Band affords wearers the ability to perceive the fluctuating hills and valleys of their electromagnetic environs. Intentional signal transmissions, and the inadvertent emanations that result from the generation and consumption of electrical power combine to form an EM “signature” that signifies the existence of a society. We are at all times bathed in this energy, as if the sky were lit up with invisible floodlights. The Energy Fluxion Band offers a keyhole through which this vast world can be observed; a glimpse of the undercurrents of our technological civilization.]

Electromagnetique Composition for Building
David Haines and Joyce Hinterding

Experimenta: Australia-Japan Media Art collaboration and exhibition (Sendai Mediatheque) Australia-Japan Media Art collaboration and exhibition, 26 Nov– 25 Dec 2006

[From website: In this work titled Electromagnetique Composition for Building, Plants & Stars the artists wrap a column on the 6th floor of the SMT building with 16km of copper wire to create a giant coil antenna that captures and amplifies the local electromagnetic energy within the building and the background noise of distant galaxies such as the Milky Way. A high definition video projection of overgrown weedy plants sits in counterpoint to the column and reveals a hidden order between the constructed and the wild.]

Life: A User’s Manual

Michelle Teran, since 2003

A User's Manual

[From the website: To understand the extent to which the multitude of transmissions circulating through the airwaves permeate cities and blur the boundaries between the private and the public, the best thing to do is go out on the street and intercept them. This is what Canadian artist Michelle Teran has been doing since 2003 with her series of interventions “Life: A User’s Manual”. Armed with a frequency scanner, Teran intercepts signals from wireless video cameras around the area she is walking in, and displays their images on a portable monitor on the street. From the analogue fog there arise ghostly non-places like hotel lobbies, banks and automatic tellers, but also spaces as private as a baby’s nursery. These walks become a real-time map of what is happening in the narrow unregulated range of the spectrum, where a series of devices operate (wireless webcams, bluetooth security cameras or mobile telephones), turning consumers into “micro-broadcasters”. For Michelle Teran, to place a camera somewhere is usually a way of protecting what it displays, and strengthening its borders. “Life: A User’s Manual” shows that the borders of physical reality do not match those of Hertzian space.]
