Magnetic Trapping

Definition

Magnetic trapping is a technique used to confine neutral atoms or charged particles using magnetic fields. This method allows scientists to manipulate the motion of atoms, making it crucial for studying low-temperature phenomena and quantum states, such as Bose-Einstein Condensation. By creating a magnetic field configuration that exerts a force on the particles, magnetic trapping can maintain a controlled environment for experiments and observations.
