Fish-tank pump

Belongs to:
Home
Synonyms:
Aquarium pump
Description:

An aquarium pump is an electric device to filter and oxygenate water of a fish tank. The electric and magnetic alternating fields at a frequency of 50 or 60 Hz are caused by the electric motor of the pump.

Frequency ranges:
  • 50–60 Hz
Type of field:
electric and magnetic
