Which metals are at the centre of the earth and produce the earth's magnetic field?
The core of the Earth is primarily composed of iron and nickel. These metals exist in a solid state in the inner core and a liquid state in the outer core. The movement of the liquid iron and nickel in the outer core generates electric currents, which in turn produce the Earth's magnetic field through the dynamo effect. This magnetic field is crucial for protecting the planet from solar radiation and maintaining conditions suitable for life.

Why do transition metals have magnetic properties?
Transition metals have magnetic properties because they have unpaired electrons in their d-orbitals. These unpaired electrons can align their spins in response to an external magnetic field, which leads to the generation of a magnetic field. This property is responsible for the magnetic behavior of transition metals.
Are all metals magnetic and all non-metals non-magnetic?
No, not all metals are magnetic and not all non-metals are non-magnetic. Some metals, such as iron, nickel, and cobalt, are magnetic, while others like gold and aluminum are not. Similarly, some non-metals, like oxygen and carbon, can exhibit magnetic properties under certain conditions.
What native metals can be found in the earths crust?
native metals
Are noble metals magnetic?
Noble metals, such as gold, silver, and platinum, are generally not magnetic. They exhibit weak magnetic properties, but they do not possess significant ferromagnetism like iron or cobalt. Some noble metals can show paramagnetism under specific conditions, but this is not a defining characteristic. Overall, noble metals are primarily considered non-magnetic.
Is magnetism a common property of metals?
No. Only a few metals can be made magnetic
Do all metals respond to magnet?
Magnetism in metals is due to electrons flowing in the same direction, causing a magnetic field. Not all metals produce a magnetic field.
What three alkaline earth metals produce a magnetic field?
None of the alkaline earth metals (beryllium, magnesium, calcium, strontium, barium, and radium) produce a magnetic field in their pure elemental form.
Where does the earths magnetic field originated from?
The Earth's magnetic field is generated by the the Earth's spin and the fact that it has molten iron in its core. When convecting molten metals spin they generate electric currents and with these a magnetic field.
Are metals all magnetic?
NOT all metals are magnetic
How do scrap yards separate metals from non magnetic metals?
They use electromagnets to separate magnetic metals from non-magnetic metals/materials in scrapyards.
Where in the interior of earth do geologists believe that the earths magnetism is influenced?
Convection of liquid metals in the outer core creates the Earth's magnetic field.
What do you have to add to a compass to make it in line with the earths magnetic field?
Nothing. That's exactly what a compass does ... as long as it's free to turn, and there are no ferrous metals or other sources of magnetic fields nearby.
Why do transition metals have magnetic properties?
Transition metals have magnetic properties because they have unpaired electrons in their d-orbitals. These unpaired electrons can align their spins in response to an external magnetic field, which leads to the generation of a magnetic field. This property is responsible for the magnetic behavior of transition metals.
Why is metal magnetic?
Metals are magnetic because of the way their electrons move. In metals, some electrons are free to move around, creating a magnetic field. This magnetic field allows metals to be attracted to magnets.
What are similarities and differences between the magnetic and electric charge interaction?
Both magnetic and electric charges interact with each other through attraction or repulsion. However, electric charges are typically carried by protons and electrons, while magnetic charges (or poles) are found in magnetic materials like magnets. Additionally, while electric charges produce electric fields that exert forces on other charges, magnetic charges produce magnetic fields that affect moving charges.
How a magnet could be used to separate different types of metals at a recycling centre?
A magnet can be used to separate ferrous metals (containing iron) from non-ferrous metals. When the magnet is passed over a mixture of metals, the ferrous metals will be attracted to the magnet and can be easily separated out. Non-ferrous metals, which are not magnetic, will not be affected by the magnet and remain in the mixture.
Are all metals magnetic and all non-metals non-magnetic?
No, not all metals are magnetic and not all non-metals are non-magnetic. Some metals, such as iron, nickel, and cobalt, are magnetic, while others like gold and aluminum are not. Similarly, some non-metals, like oxygen and carbon, can exhibit magnetic properties under certain conditions.
