For a given CA II K-line index there are too few sunspots
... The Plage index is MWO’s Magnetic Plage Strength Index MPSI: For each magnetogram taken at the 150-Foot Solar Tower, a Magnetic Plage Strength Index (MPSI) value is calculated. To determine MPSI we sum the absolute values of the magnetic field strengths for all pixels where the absolute value of the ...

Problem solving; Coulomb's Law
... Electromagnetic theory is the first unified field theory: the unification of electric and magnetic field theory, and is the subject of our study this semester and next (in 460). In Physics 230, we studied electric fields first, then magnetic fields. This is traditional, because the mathematics is a ...

... We really do need this limiting process – experimentally/in real life, the presence of a finite-singed test charge QT necessarily perturbs the source charge distribution that one is attempting to measure!! This is especially true for spatially-extended source charge distributions. As the test charge ...

... Cathode rays are not electromagnetic waves because they are deflected by electric and magnetic fields and their speed is not equal to that of light. Q2. Explain the production of cathode rays. Ans2. Cosmic rays are present in the tube which are constantly reaching the earth from the outer space. The ...
