Yes, most metals become less magnetic when heated due to a phenomenon known as thermal agitation. As temperature increases, the atomic vibrations within the metal also increase, disrupting the alignment of magnetic domains. This can lead to a decrease in the material's overall magnetic properties, a process that is particularly significant in ferromagnetic materials, which lose their magnetism above a certain temperature known as the Curie temperature.

What will be the magnetic domains of an iron nail heated up?
You need to strike the hot nail with a hammer to induce the magnetic field. This was a method that blacksmiths used to make weak iron magnets.
Why does metal become more brittle after being heated then cooled?
Not all metals do, and it depends on the rate at which the metal is cooled. Basically, in some metals the crystal pattern in the metal changes when heated- and if rapidly cooled, that pattern is sort of "locked in" to the metal. If that locked in pattern is harder or more brittle than the earlier state, the metal has become more brittle. However, heating and then SLOW cooling can make some metals less brittle- it is called annealing.
What gas is the most or least dense when heated?
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
Why don't the earth's poles attract metal?
The Earth's magnetic field is relatively weak compared to the magnetic fields produced by magnets. The magnetic attraction of the Earth's poles on metal objects is usually too weak to be noticeable at a distance. Additionally, the Earth's magnetic poles are not fixed and move over time, making them less reliable for navigating using magnetic compasses.
Why does oil become runny when heated up?
When oil is heated, its molecules gain energy and move faster, causing the oil to become less viscous and more runny. The increase in temperature decreases the oil's viscosity, making it flow more easily.

Are magnetic forces stronger when heated or cool down?
Magnetic fields are stronger when cooled down. This is because the atoms that make up the magnetic material aren't moving as fast as a heated magnet's atoms. This means that the magnetic domains are less likely to move out of place and mess up the magnetic field.

What is the effect of heat on vegetable oil?
Upon heating, vegetable oil will first become less viscous (less thick and more runny) as it is heated, and eventually, if heated hot enough it will smoke and then burn.

Why does convection happens?
convection happens because fluids become less dense and expand and riseas they are heated.
What happens to the air when heated up?
When air is heated up, the molecules within the air gain energy and move faster, causing the air to expand and become less dense. This expansion leads to a decrease in air pressure and an increase in volume.
Do heated air particles become more or less dense?
Things (almost everything, including air) becomes less dense when it is heated. So warm air rises, and cold air falls.
Will a magnetic attract gold?
No, gold is not magnetic. A gold coin that is attracted to a magnet is almost certainly gold plated over an iron or nickel base (though nickel is far less magnetic).
When air is heated the gases speed up and?
expand, causing the air to become less dense and rise.
Why does oil become runny when heated up?
When oil is heated, its molecules gain energy and move faster, causing the oil to become less viscous and more runny. The increase in temperature decreases the oil's viscosity, making it flow more easily.
