the deflexion of the needle produced bythe deflecting magnet in the given position. Reverse the deflecting magnet and proceed as above tofind <^2- Then form a table giving values of r, ^j, <;^2)<^ s ^ (^1 + «^2)> ^j sin <^ and ^r* sin </>. The last series of numbers will be… … Fig. 106. If 21 the length of the deflecting magnet is too long to be neglected,we have to replace, as in Experiment 23, the quantity r* by (r^ - //■)*/?•. The formula obtained for the broadside-on position maybe verified in the same way, but the apparatus is not quite soconvenient for this, for…
