Question
Physics 124 Lab Manual Table 3 No. of Magnets, n Length Current, Change in Magnetic Force, Magnetic Field, B FB L mass (m) (A)(Kg) How does the number of magnets affect the force between a current-carrying wire and a magnetic field? 9 10 Is it reasonable to assume that the strength of the magnetic field is directly proportional to the number of magncts? 11 Describe how your observation would change if the permanent magnetic assembly was rotated 180° that is, if the direction of the magnetic field was in the opposite direction. 12 What would happen if one of the magnets were put into the assembly backwards, with its north pole next to the other magncts' south poles? (Try if you have time) 46Explanation / Answer
answer 9. The number of magnets affet the force between a current carying wire and a magnetic field as if the two ends or poles of magnets are faced ( N-N or S-S ) a curent carrying wire then there will be more force in comparison to the magnets of opposite facing because the size of the magnetic field is increased due to more magnets.
if the magnets are stacked, the magnetic field is increased much but if magnets in a series, the effect of magnetic field is made a very small change.
