The ability of a magnetic material to retain its magnetization. The Retentivity of a material determines its use in certain magnetic applications. 3 Coercivity A measure of the resistance of a magnetic material to becoming demagnetized. The Coercivity of permanent magnets must be high to ensure lon...

Magnetic Flux: Magnetic flux is a measurement of the total magnetic field that passes through a given area. Magnetic flux is a way of describing the amount of magnetic force on something of a given area. Answer and Explanation:1 A changing magnetic field induces an electric field. If a loop...
Grapheneis a flat, single layer of carbon atoms in sheet form that is significantly stronger than steel.3It has a high surface area-to-volume ratio, high tensile strength (how much it can stretch before it breaks), and high electron mobility (the speed at which its electrons move when vol...
Who or what determines the broad areas of life and information that must never enter the minds of people and therefore the consciousness of society? Where does this eventually lead us? And finally, is there a way to escape, a way to bring full transparency and therefore sanity back into the...
The nature of the chemical bonds determines many of the molecular properties. Electrons travel in shells around atomic nuclei. Atoms are most stable when their electron shells are filled or half-filled. Covalent bonds occur when one or more electrons are shared between atoms. The electron orbits ...
The types of atoms and the way those atoms join together determines a substance's properties. Nanotechnology is a multidisciplinary science that looks at how we can manipulate matter at the molecular and atomic level. To do this, we must work on the nanoscale -- a scale so small that we ...
When an electric current flows through a wire, it generates a magnetic field. The magnetic field can be increased by coiling the wire. This allows more current to flow through a smaller distance and increases the magnetic field. The direction of the current determines the direction of the magne...
