Holmium(III) oxide - Wikipedia

Holmium(III) oxide, or holmium oxide is a chemical compound of a rare-earth element holmium and oxygen with the formula Ho 2 O 3.Together with dysprosium(III) oxide (Dy 2 O 3), holmium oxide is one of the most powerfully paramagnetic substances known. The oxide, also called holmia, occurs as a component of the related erbium oxide mineral called erbia.Typically, the oxides of the trivalent ...

Planar Magnetic vs Dynamic Headphones: Which is better?

May 05, 2020· So in summary, headphones with planar magnetic transducers often sound tighter, more controlled, and have better extension capabilities with less distortion for bass than dynamic drivers. There''s a unique ''plucked'' quality to the way tones come across, and in general, planar magnetic headphones are better at instrument separation and distinction.

Lanthanide - Wikipedia

Measuring the magnetic moment can be used to investigate the 4f electron configuration, and this is a useful tool in providing an insight into the chemical bonding. The lanthanide contraction, i.e. the reduction in size of the Ln 3+ ion from La 3+ (103 pm) to Lu 3+ (86.1 pm), is often explained by the poor shielding of the 5s and 5p electrons ...

Magnetic Material - an overview | ScienceDirect Topics

Magnetic Material. A magnetic material placed in a magnetic field (H) has a magnetic induction (B), measured in teslas (T), expressed by Equation [8.44], where μ0 is the permeability of free space (4π×10−7TmA−1) and the magnetisation, (M=m/V), is the magnetic moment (m) per unit volume (V) of the material (Oberteuf, 1974).

Magnetic cartridge - Wikipedia

A magnetic cartridge, more commonly called a phonograph cartridge or phono cartridge or (colloquially) a pickup, is an electromechanical transducer that is used to play records on a turntable.. The cartridge contains a removable or permanently mounted stylus, the tip - usually a gemstone, such as diamond or sapphire - of which makes physical contact with the record''s groove.

Neutron - Wikipedia

The neutron is a subatomic particle, symbol n or n 0, which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton.Protons and neutrons constitute the nuclei of atoms.Since protons and neutrons behave similarly within the nucleus, and each has a mass of approximately one atomic mass unit, they are both referred to as nucleons.

Deuterium - an overview | ScienceDirect Topics

In magnetic fusion, the need to cross magnetic field lines imposes an additional requirement on the fueling of the reactor: for the fuel to reach the center of the plasma, it must do so before it becomes ionized. For this reason, injecting high-velocity macroscopic frozen fuel pellets into the plasma chamber is the favored approach.
