Like Magic (VIDEO)

Paul Scherrer Institute

Caption

The video shows how the new material is forced into a loop shape with tweezers. Then a ring-shaped magnet is raised. Even if the tweezers are removed, the material retains its shape in the magnetic field. When the magnet is lowered again and the magnetic field is removed, the material returns to its original shape.
