"Magnetic" exhibition at the Palais de la Découverte, in Paris

How to explain magnetism? What is it for? Where is it found and in what form? These are the questions that the "Magnetic" exhibition will answer from November 5, 2019 to May 3, 2020 at the Palais de la Découverte in Paris.

In Paris, this is a great opportunity to for an outing with the kids this winter. During this exhibition devoted to magnetism from November 5, 2019 to May 3, 2020, the Palais de la Découverte presents the manifestations of this fascinating phenomenon and returns to its origins, bringing this natural mystery to our daily lives: what role does it play in my computer? Or, in a more general sense: what does current research tell us about the subject? Even if its effects are sometimes used to amuse and distract, magnetism is science, not magic. You can check it out for yourself through some 60 experiences that will set the pace of your visit and invite you to discover the properties of magnetism and its usefulness.

Through five sections where the public is guided from one discovery to the next, the exhibition interactively answers to a large number of questions about magnetism, a little-understood phenomenon. Through experience, manipulation and observation, the exhibition invites the public to discover the principles and effects of magnetism, which is the source of many applications in our daily lives, such as in engines, wind turbines, induction plates, subway tickets, bank cards and more

The magnet stuck to the fridge

Through an experimental stroll that stages the scientific process, the exhibition begins with an application known to all from an early age: the magnet stuck to the fridge; then, it addresses the various manifestations of magnetism and returns to the origins of a fascinating phenomenon that plays an important role in our lives, even a fundamental one for any computer user.

The Magnetic exhibition journey

About 60 new experiences divided into five thematic sections set the pace of the visitor’s journey, testing their knowledge of magnetism and inviting them to discover its various possible origins (magnets, currents, the Earth). Something to visualize the magnetic field produced by each of these origins, and thus discover certain fundamental properties of magnets, the systematic existence of a North Pole and a South Pole, and the principle of the compass.

Attraction, iron powder and ferrofluids

Visitors are invited to observe the attraction phenomena of various strengths between two magnets, then to test the intensity of the repulsive forces between them. They visualize the magnetic field produced by a magnet, first in 2D, then in space, using iron powder and ferrofluids.
Then they can test the reaction of various materials in the presence of a strong magnet and discover the magnetic field produced by an electric current, in particular through one of its applications, magnetic waste sorting. The visit is accompanied by the intervention of different scientific mediators from the Palais de la Découverte.
The journey ends with the presentation of certain experiments carried out in a material research laboratory, the Jean-Lamour Institute (CNRS-UL), part of whose activity is devoted to the creation of nanomaterials with new magnetic properties.
