Analysis The experiment about Magnetic Fields and Magnetic Force is partitioned into two sections. The first portion is about magnetic fields of permanent ma gnets and the second portion is about determining the magnetic force on a current conveying conductor. Additionally, we shall further explore on the current, length and orientation of currentcarrying wire. Our group did not encounter any problem throughout the experiment as the instructions were clearly defined, enabling our group to perform the procedures efficiently and with relative ease. For this experiment, ex periment, our group got an opportunity to visualize the nature of magnetic fields with the aid of iron fillings, calculate the magnetic force generated and determine the relationships with factors affecting its magnitude. The orientation of the magnetic field line is th at it leaves from the North Pole and arrives at the South Pole. It also proved that magnetic field lines do not intersect with each other because at any one point, there is only one direction of field. Table No. 2a No. of magnets 2 3 4 5 6

The quantity of magnets is directly proportional to its magnetic force as accumulated from our data. The relationship of magnetic force and the current and length of wire is directly proportional as well. As magnetic force follows the formula F = qvB. For the final part, the magnetic force is at its minimum at 0o and at its maximum at 90o from the formula F = ILBsinϕ ILBsinϕ. Since sin0o = 0 and sin90o = 1. The relationship is proven from the data we obtained.

Conclusion
The outcomes demonstrates that the experiment was done legitimately on the grounds that the information that are accumulated concurs with the hypotheses and equations that were exhibited. The mapping of magnetic field lines by utilizing the iron filling shows the behaviour of the interactions of magnets with the same or different polarity. From the sketch, it is observed that likes poles repel and unlike poles attract. In calculating the magnitude of magnetic force on a current carrying wire the formula : F = qvB and F = ILBsinϕ was used. In which all the factors of magnetic force is directly proportional to it. The magnetic force is max imum when the flow of current is perpendicular (90○) to the magnetic field and it is least when the stream of current and magnetic field are parallel (0○).
