1. A method of flow adjustment, the method comprising:
allowing fluid to flow through an opening in a container, wherein magnetically sensitive particles are confined within the container;
applying a magnetic field to move the magnetically sensitive particles in the container to adjust flow of the fluid through the opening; and
resetting positions of the magnetically sensitive particles using a biasing structure.
