It has been known for more than two decades that the resistance of a very pure two-dimensional conductor changes in a very particular way when an external magnetic field is applied. This quantum ...
It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...
The principle is that the electric field associated with an intense (that is, a field strength of >100 kV cm ... necessarily provide a larger THz Kerr constant than that of a molecular liquid ...
A constant field size; for example, a 25-byte name field takes up 25 bytes in each record. It is easier to program, but wastes disk space and restricts file design. Description and comment fields ...
Whilst the magnetic field strength appears to have remained relatively constant, the solar wind is known to have been significantly stronger in the past as the young Sun was more active.
