Dynamo Effect Meaning Science

A dynamo is thought to be the source of the earth s magnetic field and the magnetic fields of.

Dynamo effect meaning science. One suggestion depends on the dynamo effect. In this dynamo mechanism fluid motion in earth s outer core moves conducting material liquid iron across an already existing weak magnetic field and generates an electric current. In physics the dynamo theory proposes a mechanism by which a celestial body such as earth or a star generates a magnetic field the dynamo theory describes the process through which a rotating convecting and electrically conducting fluid can maintain a magnetic field over astronomical time scales. The word dynamo from the greek word dynamis δύναμις meaning force or power was originally another name for an electrical generator and still has some regional usage as a replacement for the word generator the word dynamo was coined in 1831 by michael faraday who utilized his invention toward making many discoveries in electricity faraday discovered electrical.
