became the first commercial rare-earth and transition-metal permanent magnets. In 1976 an alloy of samarium cobalt with trace elements (iron, copper and zircon) was developed, with a molecular structure of Sm2(Co, Fe, Cu, Zr)17. These magnets have great potential for use in...
What are magnetic elements? Give example. 01:47 What are metals? 03:24 What are non-metals? 04:00 What would happen if magnesium wire is burnt in air? 01:31 Though hydrogen is a gas it is placed in activity series why? 02:23 Write some uses of Graphite 03:19 It is possible to ...
A permanent magnet is made of steel and loses its magnetism easily. View Solution Permanent magnets are made using View Solution The permanent magnet is made fron which one of the following substances? View Solution PRADEEP-MAGNETIC EFFECTS OF ELECTRIC CURRENT-Additional Questions A. (very short)...
What are magnetic fields made of? What type of elements are used to make n- type semiconductor? Often, when people have to work around radioactive materials spills, we see them wearing white coveralls (usually a plastic material). What types of radiation (if any) do you think these suits...
What are the 4 forms of matter? Which is a brittle material that is stronger than most metals and is commonly used in magnets? a. alloy b. ferrite c. nickel d. cobalt What is a magnetic domain? List the noble gas elements. What happens to the resistance of most common metals as the...
Regardless, you can bend all types of flexible magnets without breaking them. The same can’t be said for other types of magnets, which are typically too hard and rigid to break. Ferromagnetic Compound Most flexible magnets are made of a ferromagnetic compound. The term “ferromagnetic” is ...
The other components of an alloy (which are called alloying agents) can be either metals or nonmetals and they're present in much smaller quantities (sometimes less than 1 percent of the total). Although an alloy can sometimes be a compound (the elements it's made from are chemically ...
Brass is a mix between Zincand Copper. These two primary elements are not magnetic. When they form together, they will also create a non-magnetic compound. In essence, brass will not interact with moving magnets. It shares similar features with aluminum, copper, and zinc. Brass was often use...
Yes. Ferrite magnets are made up of a large mixture of chemicals that are extremely strong and durable. Although, the ferrite magnet still comes weaker than neodymium magnets. Conclusion Ferrite magnets are a type of magnets that are strong, durable, and useful for different purposes. Also, the...
Both the magnet frame and the metal plate are made of aluminum. Aluminum magnetic catches are lightweight, durable and highly resistant to corrosion. They also offer a sleek chrome finish that’s aesthetically pleasing. Brass Brass is commonly used in the construction of magnetic catches. Brass,...
