This use for diamonds is based on the requirement for the tip of the needle to conduct signals from the vinyl into the player's other components, and their ability to out-last all other options for needle tips.
If you bring two compasses next to each other, the magnetic fields of the compass needles will interact. The magnetic needles will align themselves in opposite directions, causing the compass needles to repel each other.
Compass needles are typically made from magnetized materials such as iron or steel. These materials are able to become magnetized and align with the Earth's magnetic field, allowing the compass needle to point north.
It requires significant pressure, around 725,000 pounds per square inch (psi), and temperatures of about 2,200 degrees Fahrenheit (1,200 degrees Celsius) to convert coal into diamonds through a process called high-pressure, high-temperature synthesis. This process mimics the natural conditions in the Earth's mantle where diamonds are formed.
Diamonds shine and sparkle due to their high refractive index, which causes light to bounce around inside the diamond and reflect back to the viewer. This phenomenon is known as total internal reflection. Additionally, the diamond's crystal structure and facets play a role in dispersing light in a way that creates the characteristic sparkle.
Diamonds are the hardest mineral known. However, a flaw in a stone presents a weak spot, and if the stone is hit 'just right', the stone may fracture along the flaw. However, most diamonds are graded so that stones with visible flaws -- rated as Included -- (most susceptible to chipping or fracturing) are clearly identified, and would therefore be set in such a way so as to protect the stone.
Osmium
Yess! of couse! plus the d jays use them
you are going to ruin the record.... record needles are not made of metal they are made of teflon cause metal scrapes away the grooves in the record
All diamonds are formed from carbon.
needle
Yes, pine needles can make soil acidic as they release acidic compounds as they decompose.
Diamonds are formed from carbon.
Mined diamonds are elements -- minerals. Man-made diamonds can be fabricated out of carbon.
No. Diamonds are mined in South Africa.
insectivora + needles
They make diamonds.
