Soon after Rutherfords scattering theory had been confirmed by experiment (about 1913), the one-to-one association of an atomic number Z with each element was solidified by the work of Henry Moseley (1887- 1915). electric field situation and the magnetic field situation is that the magnetic field lines are complete loops.

Indeed, all field lines that go through it must form a closed loop, so they must come back from the outside, so they must turn (but as they go back, they spread out, so the field strength will tend to zero). an external magnetic field, is affected by a number of factors including materials, microstructure and geometry of the constituent layers, and strength and direction of applied magnetic field.
If the magnetic field is perpendicular to the direction of particles motion, then we have, If the term magnetic field is used to refer to a quantity rather than a region, it is most likely referring to the magnetic field The difference in the scale reading (in grams) is a measure of the force of the top magnet on the bottom magnet. If a ruler is also used to measure the separation of the magnets, then we can measure the Force and Distance relation. Note the reading on the scale is proportional to the force between the bar magnets. That

Ampere's law applied to an infinitely-long wire predicts a magnetic field of strength B = 0 I/(2r) a radial distance r from the wire. Its polar field is 12 gauss (0.00010.0002 T sunspots and 10100 gauss (0.0010.01 T) in solar prominences. The Magnetic Field strength at that distance is 599 Gauss. Now, look at a big 1" cube, (BX0X0X0). We'll plug in a distance value equal to 1" in this case, and the calculator again indicates 599 Gauss. The bigger magnet is projecting the magnetic field over a much larger area and distance than the little one. A: Close to the magnet, that depends on the detailed shape of the magnet. It is a state of matter in which an ionized substance becomes highly electrically conductive to the point that long-range electric and magnetic fields dominate its behaviour.. Magnetic fields can be combined to be stronger or weaker depending on how they are put together. This head-on approach generates an output signal, V H which in the linear devices represents the strength of the magnetic field, the magnetic flux density, as a function of distance away from the hall effect sensor. Magnetic force obeys an inverse square law with distance.If the distance between two magnets is doubled the magnetic force between them will fall to a quarter of the initial it obeys an inverse square law with distance).

The word pseudoscience is derived from the Greek root pseudo meaning false and the English word science, from the Latin word scientia, meaning "knowledge".Although the term has been in use since at least the late 18th century (e.g., in 1796 by James Pettit Andrews in reference to alchemy), the concept of pseudoscience as distinct from real or proper science
