ANALYSIS
In perf perfor ormi ming ng the the expe experi rime ment nt,, the the firs firstt part part tack tackle les s abou aboutt the the magnet magnetic ic field field of perman permanent ent magnet magnets. s. In this this part, part, differe different nt set-up set-ups s of magnets are observed and within each set-up are invisible magnetic fields. Using iron filings on a sheet of paper, a corresponding sketch of the set-up’s magnetic field can be acquired after shaking. Since iron is a kind of metal, the magnet will attract and show the path in which the iron filings are attracted. In the first set-up of the magnets, two magnetic bars with like poles are faced against each other. fter the filings are placed and shaken, the iron iron filin filings gs form formed ed curv curved ed line lines s show showin ing g a defle deflect ctin ing g patte pattern rn from from the the opposite poles. In the second set-up of the magnets, two magnetic bars with unlike poles are faced against each other. fter placing the filings and shaken, shaken, the iron filings behaved in such a wa! that the poles attract each other. In the third set-up of the magnets, two U-magnets with their unlike poles are faced against each other. "he behavior of the magnetic field is the same same as the second second set-up set-up.. #ot #oth h the U-magnets U-magnets themselve themselves s pro$ec pro$ectt an attractive pattern to its opposite poles while also making an attraction to the opposite U-magnet’s unlike pole. "hus, making a square shaped magnetic field. In the fourth set-up of the magnets, two U-magnets with their like pole poles s are are face faced d again against st ea each ch othe otherr and and an iron iron ring ring was was plac placed ed at the the cente%r. "he behavior of the magnetic field is somewhat like a whirlpool. lso, there was no magnetic flux that inside the iron ring. "he lines pass through the iron ring that serves as the bridge wherein the magnetic flux flows. "he second part of the experiment tackles the relationship between the magnetic force and a current-carr!ing conductor. &or table a, it can be noticed that the number of magnets is directl! proportional to that of the magnetic force. "he more magnets inserted in the assembl!, the heavier the mass which will result to a higher magnetic force acquired. &or table b, different currents are tested to determine its relationship with with the result resulting ing magnet magnetic ic force. force. It can be no notice ticed d that that the increasin increasing g
current is resulting to an increasing magnetic force. "hus, current is observed to be directl! proportional to the magnetic force. &or table c, different current loops are tested to identif! its relationship with the magnetic force. #ased on the data acquired, it can be noticed that the change in current loop 'specificall! the length( is directl! proportional to the magnetic force. longer length will result to a higher magnetic force. &or table d, different angles are tested whether how it affects the resulting magnetic force. #ased on the data acquired, the magnetic force increases as the angle increases while turning the angle to the opposite direction will result to a same magnitude but negative magnetic force. In performing the experiment, errors ma! result from different sources. n example is improper orientation of the magnets in the assembl!, failure to read the manual properl! and mishandling the laborator! apparatus.
CONCLUSION
#ased on the acquired data and anal!sis, I can sa! that we are able to accomplish the required ob$ectives for the experiment. )e are able to understand the nature of magnetic fields around the poles of magnets. *ike magnetic poles will repel each other while unlike magnetic poles will attract each other. )e are also able to identif! that the magnetic field, current, length and orientation of current-carr!ing wire are all directl! proportional to the resulting magnetic force. n increase to these values will result to an increase in the magnitude of the resulting magnetic force. lso, the magnitude of the magnetic force on a current-carr!ing wire is also the same as determining weight. "he magnetic force is measured b! digital weighing balance in which it is measured in grams. +onverting the quantit! to kilograms and then multipl!ing the gravitational acceleration, the force in ewton is determined. "hese equations prove that current, length, magnetic field and orientation of the current-carr!ing wire is directl! proportional to the magnetic force. In the experiment, the current serves as the charged particles entering through the magnetic field which results to magnetic force.
