Measuring faint magnetic fields is useful in a number of areas, including mapping brain activity, monitoring hearts and probing fundamental physics. Typically, picking up such weak signals requires expensive or bulky equipment, ...
From schools of fish and flocks of birds to microscopic synthetic particles, many systems in nature and the laboratory consist of individual units or agents that move by consuming energy. These systems are known as active ...

A diamagnetic substance is slightly repelled by magnetic fields. With a strong enough magnet, the diamagnetic force can override gravity, and the substance will float in the air. Graphite, the main component of pencil lead, ...
