2. Programmable magnet - Wikipedia

   en.wikipedia.org/wiki/Programmable_magnet

   Correlated magnets can be programmed to interact only with other magnetic structures that have been coded to respond. Correlated magnets can even be programmed to attract and repel at the same time. Compared to conventional magnets, the correlated magnet provides much stronger holding force to the target and stronger shear resistance.

3. Electropermanent magnet - Wikipedia

   en.wikipedia.org/wiki/Electropermanent_magnet

   Electropermanent magnets made with powerful rare-earth magnets are used as industrial lifting (tractive) magnets to lift heavy ferrous metal objects; when the object reaches its destination the magnet can be switched off, releasing the object. Programmable magnets are also being researched as a means of creating self-building structures. [2] [3]

4. Magnetism - Wikipedia

   en.wikipedia.org/wiki/Magnetism

   Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.

5. Bird control - Wikipedia

   en.wikipedia.org/wiki/Bird_control

   Bird control or bird abatement involves the methods to eliminate or deter pest birds from landing, roosting and nesting. Bird control is important because pest birds can create health-related problems through their feces, including histoplasmosis, cryptococcosis, and psittacosis. [1] Bird droppings may also cause damage to property and equipment.

6. Magnetic levitation - Wikipedia

   en.wikipedia.org/wiki/Magnetic_levitation

   Magnetic materials and systems are able to attract or repel each other with a force dependent on the magnetic field and the area of the magnets. For example, the simplest example of lift would be a simple dipole magnet positioned in the magnetic fields of another dipole magnet, oriented with like poles facing each other, so that the force ...
