The needle in a compass is typically called a magnetic needle or magnetic pointer.
Magnetic name badges can be purchased from office supply stores, online retailers like Amazon and eBay, specialty badge manufacturers, and promotional product companies. It's important to ensure that the magnetic name badges are strong enough to securely hold in place without causing any damage to clothing.
Magnetic ink is exactly what the name indicates; it is a kind of ink which is both visible to the eye (it's black) and has a magnetic field that can be detected with the right kind of magnetometer. It is used in the coding on the bottom of checks, known as routing numbers, so that it can be read both by people and by computers.
Plasma includes ions (charged particles), electrons, neutrons, photons, and various atomic and molecular species. It can also contain impurities, dust particles, electric and magnetic fields, and waves.
Atomos is the name Democritus gave the smallest particles.
'Magnetic North' is the name of a location, or a direction, and has nothing to do with the magnetic polarity of that region. In fact, its magnetic polarity is a south pole, which accounts for why it attracts the north pole of a magnet or compass (unlike poles attract).
'Magnetic North' is the name given to a location in the Arctic, to differentiate it from 'True North'. Whereas True North is fixed and located at the Earth's axis of rotation, the 'Magnetic North' varies from year to year. The term, 'Magnetic North', does not describe the magnetic polarity at that location which, actually, is a south pole.
Ferrofluid is the name of the liquid magnetic substance. It is composed of tiny magnetic particles suspended in a carrier fluid, like oil or water. Ferrofluid is known for its unique properties, such as becoming magnetized in the presence of a magnetic field.
First of all, it's important to understand that 'Magnetic North' is a location (or, more accurately, a direction), and not a magnetic polarity.The end of the compass needle (or magnet) that points in the direction of 'Magnetic North' was, for obvious reasons, originally called its 'North-seeking pole'. Over time, the term 'seeking' has fallen into disuse, and we now simply call it its 'north pole', which by general agreement is also the magnetic polarity of that end of the needle (or magnet). Because, unlike poles attract, this means that the magnetic polarity of the location we call 'Magnetic North' is south.
The area surrounding Earth that is influenced by Earth's magnetic fields is called the magnetosphere. Its primary function is to protect the planet from the solar wind and cosmic rays by deflecting charged particles.
Reversibility
Actually, you have it reversed: Heparin in the generic name for CALCIPARINE.
yes. it says it in its name.
Magnetic rock is called Lodestone.
The number assigned to each solvent to describe its polarity is called the dielectric constant.
magnetic variation
It does what the name emply it changes the function or polarity OS a signal.
