What is a superconductor?
—A superconductor is a material that can conduct electricity with zero electrical resistance when cooled below a certain temperature, called the critical temperature.
What is ferrofluid?
—Ferrofluid is a liquid that contains tiny ferromagnetic particles, usually made of iron or iron oxide. When exposed to a magnetic field, the particles align and create fascinating patterns and shapes.
Why does ferrofluid follow magnetic field lines?
—Ferrofluid is made up of nanoparticles of iron, and when a magnetic field is applied, the nanoparticles align with the field, creating the spiky pattern that follows the magnetic field lines.
How does the density of ferrofluid change?
—The density of ferrofluid can change when exposed to a magnetic field, causing it to rise or sink depending on the field strength. This behavior is due to the movement of the nanoparticles within the fluid.
What practical applications do superconductors and ferrofluid have?
—Superconductors have applications in various fields, including energy transmission and medical imaging. Ferrofluid is used in technologies such as loudspeakers, seals, and magnetic sensors.
