ferromagnetic substance मीनिंग इन हिंदी

उदाहरण वाक्य

1. Due to saturation, the magnetic permeability ? f of a ferromagnetic substance reaches a maximum and then declines
2. However, in paramagnetic and ferromagnetic substances, the diamagnetic effect is overwhelmed by the much stronger effects caused by the unpaired electrons.
3. In paramagnetic and ferromagnetic substances the weak diamagnetic force is overcome by the attractive force of magnetic dipoles in the material.
4. Every ferromagnetic substance has its own individual temperature, called the Curie temperature, or Curie point, above which it loses its ferromagnetic properties.
5. Neel discovered that a ferromagnetic substance like iron loses its magnetism as it is heated and that other materials, not normally magnetic, behave like iron at higher temperatures.
6. Spin glasses differ from ferromagnetic materials by the fact that after the external magnetic field is removed from a ferromagnetic substance, the magnetization remains indefinitely at the remanent value.
7. Among Pierre Curie's discoveries were that ferromagnetic substances exhibited a critical temperature transition, above which the substances lost their ferromagnetic behavior-this is known as the " Curie point . " He was elected to the Academy of Sciences ( 1905 ), having in 1903 jointly with Marie received the Royal Society's prestigious Davy Medal and jointly with her and Becquerel the Nobel Prize for Physics.
8. To show these blood flow changes were related to functional brain activity, they changed the composition of the air breathed by rats, and scanned them while monitoring brain activity with EEG .; } } The first attempt to detect the regional brain activity using MRI was performed by Belliveau and others at Harvard University using the contrast agent Magnevist, a ferromagnetic substance remaining in the bloodstream after intravenous injection.
9. In ferromagnetic substances like iron and in plasmas, magnetic forces can be understood by imagining that the field lines exert a tension, ( like a rubber band ) along their length, and a pressure perpendicular to their length on neighboring field lines .'Unlike'poles of magnets attract because they are linked by many field lines;'like'poles repel because their field lines do not meet, but run parallel, pushing on each other.
