A permanent magnet is always on; there isn't any way to turn it off. An electromagnet can be controlled; you can turn it on or off, or change the amount of magnetism by varying the current passing through the coils.
a naturally occurring magnet composed of a form of iron called magnetite
Yes, oil is a natural resource that is formed from organic matter over millions of years. It is extracted from the ground and used for various purposes such as fuel, lubrication, and the production of plastics.

Natural amber is formed from fossilized tree resin over millions of years, while synthetic amber is created in a laboratory using artificial resins. Natural amber often contains inclusions like insects or plant matter, while synthetic amber is usually free of inclusions. Additionally, natural amber tends to have a higher value and is considered more valuable than synthetic amber in the jewelry market.
Artificial magnets can be tailored to have specific magnetic properties and shapes, ensuring they are suitable for various applications. In contrast, natural magnets, such as lodestone, are limited in their magnetic strength and shapes, making them less versatile for modern technology. Additionally, artificial magnets are more affordable and easier to produce in large quantities compared to natural magnets.
Advantages of artificial fibers include durability, resistance to wrinkles, and ability to be produced in a wide range of textures and colors. Disadvantages include potential environmental harm from production processes, tendency to pill or break down over time, and less breathability compared to natural fibers.
One advantage of a natural magnet is that it does not require any external power source to maintain its magnetic properties, unlike an electromagnet that requires electricity to operate. Natural magnets are typically more stable and retain their magnetism for a longer period of time compared to electromagnets that can lose their magnetic properties when the electric current is removed.

Gas boilers provide a deeper, more natural cooking taste and flavor to your food as opposed to electric heat which is artificial and sometimes does not provide accurate temperatures for your food.

Natural levees are built up over time from debris and sediment whereas artificial levees are man made using sand bags and larger rocks.
Artificial selection tends to occur more quickly than natural selection because it involves intentional breeding by humans to promote desired traits in organisms. This focused approach can lead to rapid changes in specific characteristics over a few generations. In contrast, natural selection operates through environmental pressures and can take much longer for significant changes to occur, as it relies on random genetic variations and survival advantages over time.
Some are natural, and some are not. The natural kinds are based on herbs and similar things found in nature. The artificial stimulants are not beneficial to the body over long-term.
