- 1.) Should the speed at which a magnet is moved through a coil of wire affect the measured peak voltage across the coil? If so, how? 2)If a magnet is moved through a coil of wire South pole first instead of North pole first, how should the measured voltage response be affected? 3) Should the number of individual coils in the wire have an effect on the measured emf? If so, how? 4) Below draw a graph of the expected magnetic flux through a point in the coil as a function of time as the magnet passes through the coil.S2 В Plate PIP B' Bainbridge's mass spectrometer, shown in the figure above, separates ions having the same velocity. The ions, after entering through slits, Si and S2, pass through a velocity selector composed of an electric field produced by the charged plates P and P', and a magnetic field B perpendicular to the electric field and the ion path. The ions that then pass undeviated through the crossed E and B fields enter into a region where a second magnetic field B' exists, where they are made to follow circular paths. A photographic plate (or a modern detector) registers their arrival. Assume r is the radius of the circular orbit, derive ratio g/m for the ions.
