Abstract: A dry powder delivery device may be configured to provide micronized dry powder particles to airways of a user. The device may include a cylindrical container delimiting a chamber containing at least one magnetically-responsive object, a motor external to said chamber, a magnet external to the chamber and rotatably coupled with the motor, and an outflow member configured to direct airflow to a user. The magnetically-responsive object may be coated with micronized dry powder particles, and the motor may be operable to rotate the magnet about an axis. Rotation of the magnet creates a magnetic field that causes the magnetically-responsive object to move in response to the magnetic field and collide with a side wall of the container to deaggregate the dry powder particles and aerosolize the dry powder in the chamber.
