The brushes, where the brushed motor gets its name from, conducts electricity from the battery to the commutator. The commutator acts like an electric switch, changing the eletromagnet polarity which acts against the external fixed magnets to push or pull which in turn creates a rotational motion. Typically, the brushes in a brushed motor are typically made of carbon as carbon is conductive, fairly soft and will wear before the metallic fingers on the commutator.

The first battery was accidentally discovered through a twitching frog leg and the lead-acid battery in your car can still trace its roots back to that 18th century invention by Italian physicist Alessandro Volta in the sense that its still based on the same principle and is still very much 'alive' - Feed and look after it and it'll serve you for many years, neglect it and it'll die a slow and painful death and might even leave you stranded by the roadside.

If a stitch in time saves nine, a strip of double-sided tape in time would probably save nineteen (Ringgit and eight Sen with GST to be exact)! It all started when our colleague arrived at CT Hardware HQ on Monday morning to find the rear of his car 'plate-less'.
