Define Dynamo Effect Science

The idea is that a current producing a magnetic field is itself produced by the magnetic field that it generates in the same way that a dynamo.

Define dynamo effect science. Dynamo definition an electric generator especially for direct current. The results of our study support the idea that galaxy magnetic fields are generated by a rotating dynamo effect similar to the process that produces the sun s magnetic field sui ann mao minerva research group leader for the max planck institute for radio astronomy in bonn germany said. Other articles where dynamo effect is discussed. 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.

If a plasma moves perpendicular to a magnetic field an electromotive force according to faraday s law is generated in a direction perpendicular to both the direction of flow of the plasma and the magnetic field. One suggestion depends on the dynamo effect. Dynamo synonyms dynamo pronunciation dynamo translation english dictionary definition of dynamo. The dynamo effect is a geophysical theory that explains the origin of the earth s main magnetic field in terms of a self exciting or self sustaining dynamo.

In this dynamo mechanism fluid motion in the earth s outer core moves conducting material liquid iron across an already existing weak magnetic field and generates an electric current. Dynamics definition the branch of mechanics that deals with the motion and equilibrium of systems under the action of forces usually from outside the system. It is the self generation of a magnetic field by a conducting body moving in an initially weak or zero magnetic field. The dynamo effect refers to a set of theories to explain how a magnetic field is generated in a celestial body such as the earth.

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