What would happen if a strong magnet passed an object with magnetic domains arranged randomly?
most of the domains line up so that the north pole of the object is attracted to the south pole of the magnet.
What temperature is required for a bimetallic strip to bend?
Any temperature above or below the temperature at which they were glued together.
What does degrees above zero mean?
Country that there temperature is above zero degrees
A calorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same .?
Many principles are used. Expansion of liquids. Production of thermo emf. Variation of resistance of conductors. As temperature changes certain physical properties change as mentioned above. Such changes are used to know about the temperature.
What is the temperature at which Argon ia a gas?
Above 87.3 K.
What happens above Curie temperature?
Above the Curie temperature ferromagnetic elements and materials lose this characteristic.
What do you mean by Curie point?
Curie point is the temperature above which a ferromagnetic substance behaves as a paramagnetic substance.
Is atomic number 64 magnetic?
Gadolinium is ferromagnetic at temperatures below 20 °C and is strongly paramagnetic above this temperature.
When a material is melting the temperature?
When a material is melting, the temperature is likely to be increasing. That or the temperature is just above the material's melting/freezing point.
What is the definition of a magnet?
A permanent magnet is a magnet that has been manufactured to "permanently" hold its magnetic field. Ferromagnetic material of a desired shape is heated above its Curie point, exposed to a large electromagnetic field, and cooled slowly while being held in that field. This allows the magnetic domains in the material to align themselves with the field of the electromagnet. Further, when the material cools below its Curie point, the magnetic domains will remain in the position they are in when the electromagnet is shut off. The magnet is now a permanent magnet; the magnet "holds" the magnetic field "imprinted" on it.
Will magnetite attract?
Generally speaking, any ferro-, ferri-, or para- magnetic material. (Where the curie temperature is above the material temperature.
What will magnetite attract?
Generally speaking, any ferro-, ferri-, or para- magnetic material. (Where the curie temperature is above the material temperature.
The effect of temperature on magnetization?
Each material which can be magnetized has a material specific, so called Curie temperature. Above this specific temperature the material will lose its magnetism and the ability to be magnetized. Returning below this temperature, the material regains its magnetic properties.
What is curie point or curie temp of a magnet?
the temperature depends on what material you are using such as iron. it als depends on the size of the magnet
What is a ferromagnetic element?
Some ferromagnetic elements are: Iron Nickel Cobalt Gadolinium Dyprosium Ferromagnetic means- a substance such as iron in which the magnetic moments of the atoms spontaneously line up with each other, making a large net magnetic moment. Ferromagnets lose their ferromagnetism when heated above a specific temperature (called the Curie point), because the thermal energy melts the magnetic alignment, a bit like the way crystals melt when heated.
How do the atoms differ in materials that can be useful as magnets and materials that cannot?
The primary difference is that in materials that can be used as magnets, the atoms can form what are called magnetic domains. Individual atoms and small groups of them form these domains, and the domains can be caused to "face the same way" when exposed to a magnetic field. When the field that aligned them is removed, some of the domains don't return to their previous orientation. They stay aligned leaving a residual magnetic field. The materials that cannot be used magnets don't have magnetic domains. If you heat magnetic material and expose it to a strong magnetic field while it's hot (like at or above its Curie temperature), and then you apply a strong magnetic field and maintain the field while cooling it down, the field "impressed" on the material will largely stay there and you've made a permanent magnet.
An experiment yielded the above temperature and time information What is the freezing point of the material in this experiment if the material is a solid at time zero?
0 degrees celsius
