What do magnets have to with electricity?
Faraday showed that a wire passing through a magnetic field will produce electricity. This is how a generator works. Many windings of wire on an armature spin in a magnetic field. This makes electricity.
What Did Hans Christian Oersted invent?
His contribution was the electric currents create magnetic fields, an important aspect of electromagnetism...
Where did Hans Oersted live?
Hans Christian Ørsted (or Oersted) lived in Denmark. He discovered the magnetic field produced by an electric current.
Why does iron attract to magnet?
Magnet are objects which have an electromagnetic force. It attracts iron and other metals which have the property of being induced by a magnets effect and repels other magnets.
What makes the rapid-decay theory more scientifically valid than the dynamo theory?
The rapid decay theory explains the decrease in the strength of the earth's magnetic field better then the dynamo theory. Although the dynamo theory explains the explains the reversals where the field pointed in the opposite directions better. The rapid decay theory allows for it, but only if there is an event of cataclysmic volcanic and geological activity. The rapid decay theory also explains the magnetic fields on the other planets correctly.

Are convection currents responsible for the magnetic field?
Yes, of course...
Earth is like a giant magnet because of convection currents in the?
Earth's outer core, composed of molten iron and nickel, experiences convection currents due to heat from the inner core. These currents generate the Earth's magnetic field, acting like a giant magnet with a north and south pole. The movement of these convection currents creates the magnetic field that surrounds and protects the planet.
What is one result of convection currents in earths outer core?
One result of convection currents in Earth's outer core is the generation of Earth's magnetic field. As the hot, molten iron in the outer core moves in a circular motion due to convection currents, it creates a dynamo effect that generates the magnetic field.
What causes magnetic pole?
The Earth's magnetic field is believed to be generated by electric currents in the conductive material of its core, created by convection currents due to heat escaping from the core.
What are sources make up the earths magnetic field?
The earth's magnetic field is caused by convection currents in our core. The core is made out of iron, which is a magnetic metal.
Where does the convection occur that causes the Earth's magnetic field?
Convection occurs in the Earth's outer core, where the movement of molten iron and nickel creates electric currents. These electric currents generate the Earth's magnetic field through a process known as the geodynamo.
Magnetic striping is evidence of?
pole reversals seafloor spreading
When the convection that causes earths magnetic field happens in earths what?
When convection occurs in Earth's outer core, it generates electric currents due to the movement of the molten iron and nickel. These electric currents create a magnetic field around the planet, known as the Earth's magnetic field. This magnetic field plays a crucial role in protecting Earth from solar winds and cosmic rays.
How was Allan Cox contributing to the theory of continental drift?
Cox contributed to continental drift theory by researching and proving that the seafloor spreads and that the Earth has experienced magnetic reversals. He did this by studying the layers of volcanoes and streambeds.
