Fluid

The video tutorial explains that both liquids and gases are types of fluids. It introduces ferro fluids, which are liquids containing tiny magnetic particles. When exposed to a magnetic field, these particles become magnetized, causing the ferro fluid to behave like a solid. However, upon touching, it is evident that they remain fluid.

What are the two types of fluids mentioned in the text?

What are ferro fluids and what do they contain?

What happens to the particles in a ferro fluid when placed in a magnetic field?

How do the particles in a ferro fluid behave when they are magnetized?

What observation can be made when touching the spikes of a ferro fluid with a splint?
