Electric motor. This consists of a loop of wire that is free to rotate in a magnetic field (yellow arrows).
The loop is attached to a power source (left), which drives a current (blue arrows) around the wire. The loop is connected to the power source through a commutator, a pair of half rings, which reverses the flow of current when the loop...

Cutting sodium metal with a scalpel.
The shiny exposed metal surface reacts rapidly with oxygen and water in the air, forming a duller layer of sodium oxide and hydroxide. Then the sodium metal is dropped into water. The reaction produces hydrogen gas and sodium hydroxide....

The double-helical configuration that DNA strands reside in makes them difficult to separate, and yet they must be separated by helicase proteins if other enzymes are to transcribe the sequences that encode proteins, or if chromosomes are to be replicated

Nitrogen atom. Diagram of an atom of the element nitrogen, pulling back from the central nucleus to reveal the surrounding electron orbitals.
Nitrogen is the seventh element, and has seven protons (red) in its nucleus, along with seven neutrons (blue). Nitrogen has seven electrons, and each of its orbitals can hold a maximum of two. Orbitals are filled from the lowest energy...

Rotating triangular prism refracting light.
Materials, such as glass, change the speed of a light beam passing through it (refraction). A beam of white light is consequently split into its constituent colours of varying wavelengths (a rainbow). This process is known as dispersion
