Magnetic trapping

Definition

Magnetic trapping is a technique used to confine and manipulate particles, such as atoms or ions, using magnetic fields. This method allows researchers to isolate and study these particles at extremely low temperatures, which is crucial for phenomena like Bose-Einstein condensation. By using magnetic fields, it's possible to create conditions that prevent particles from escaping, enabling detailed exploration of their quantum behaviors.
