It is made of glass and silver plate which are nonmagnetic. The plate on the glass could also be aluminum but still not affected much by an external magnetic field. As long as the flask has no iron, nickel, or cobalt (ferromagnetic elements) it would be called nonmagnetic. Note all materials are affected by a magnetic field, but it is very much a subtle effect for most things we call nonmagnetic.

What did James dewar invented?
James Dewar invented the Dewar flask in 1892, a type of vacuum flask that can keep its contents hot or cold for long periods of time. He also worked on the liquefaction of gases and was known for his research in cryogenics.
The surfaces of a dewar flask are silvered for the purpose of minimizing heat transfer by what process?
The surfaces of a dewar flask are silvered to minimize heat transfer through radiation. The silver coating reflects thermal radiation, preventing heat from entering or escaping the flask. This helps maintain the temperature of the contents inside the dewar flask for longer periods.
What company patented invention James Dewar denying him credit?
The company that patented the invention James Dewar denied him credit for is Thermos LLC. Dewar's vacuum flask design was patented by Thermos in 1904, leading to the creation of the iconic Thermos flask. Dewar did not receive royalties or recognition for his contribution to the invention.
Why is the Dewar flask important?
A Dewar flask is important because it can keep its contents hot or cold for long periods due to its vacuum-insulated design. It is commonly used in laboratories to store and transport liquid nitrogen, samples, or other temperature-sensitive materials. Its ability to maintain temperature stability makes it crucial for various scientific experiments and processes.
Who invented the cryogenics?
James Dewar is credited with inventing cryogenics in the late 19th century. He developed the first vacuum flask, known as the Dewar flask, which laid the foundation for the field of cryogenics by allowing for the storage and manipulation of materials at extremely low temperatures.

Is dewar flask contains liquid air?
A dewar flask is a type of vacuum flask designed for storing and transporting very cold liquids like liquid nitrogen and liquid helium, which are commonly used in laboratories for various applications. Liquid air typically refers to a mixture of liquid nitrogen and liquid oxygen, so a dewar flask can technically hold liquid air if it is a mixture of nitrogen and oxygen.
