What are two advantages of a electro magnet over natural magnet?
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.
Is a magnet made of lodestone?
a naturally occurring magnet composed of a form of iron called magnetite
Is oil a natural resource?
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.
Why magnet keepers use to store magnets?

What are the key differences between natural amber and synthetic amber?
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.
Why are artificial magnets preferred over natural magnet?
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.
What are the advantages and disadvantages of artificial fibers?
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.
What are two advantages of a natural magnet over electromagnet?
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.
How many artificial satellites circle the earth?
over a thousand artificial satellites. the first artificial satellite was sputnik. the only natural satellite earth has is the moon

What are the advantages of gas boilers over electric heat?
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.
What the difference between natural levees and artificial levees?
Natural levees are built up over time from debris and sediment whereas artificial levees are man made using sand bags and larger rocks.
Which tends to occur more quickly natural selection or artificial selection?
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.
Who said artificial maple syrup is bad?
Concerns about artificial maple syrup primarily stem from health advocates and some food scientists who argue that synthetic additives and flavorings can be less healthy than natural alternatives. These critics often highlight the importance of consuming whole, unprocessed foods. Additionally, some maple syrup producers and organizations promote the benefits of pure maple syrup, emphasizing its natural origins and nutritional advantages over artificial products.
What are the advantages and disadvantages of using astro turf?
Astro-Turf (which is a specific brand of artificial turf, or grass) has several advantages over a natural grass surface. It tends to stand up under heavy use better than grass, it can be used in indoor arenas and because it does not need to be cut is easier to maintain. However artificial turfs tend to be more abrasive than grass, causing burn like injuries, and some research has shown older artificial turfs present a greater potential for joint injury.
