Shown in the given diagrams (a), (b) and (c) are the magnetic fields around different systems. Identify them. Compare the pattern of the field lines in all the three systems.
Answers
Answer:
The close continuous curves in a magnetic field are called magnetic lines of force. Curved lines are used to represent a magnetic field, drawn such that the number of lines relates to the magnetic field's strength at a given point and the tangent of any curve at a particular point is along the direction of magnetic force at that point.
The magnetic lines of force are uniform and strong at the point C and they diverge as they move towards points A and B and the distance between the lines increases. At this point when we consider points A and B, the magnetic lines of force at B seem to be more divergent than A. Eventually, the strength of the magnetic field is weaker at B where the lines are far and they strengthen as closeness increases.
Hence, the magnetic field is weakest at the point B compared to A and C.
