Explanation

MagneticPole Structure:
- Represents a magnetic pole with its position (x, y)
  
  Advertisement
  
  and strength.
MagneticFieldVector Structure:
- Represents a magnetic field vector with direction components (x, y) and magnitude.
calculateField Function:
- Takes a vector of magnetic poles and a point (px, py)
  
  Advertisement
  
  as input.
- Calculates the magnetic field vector at the point by summing the contributions of each pole.
- Uses the formula fieldStrength = pole.strength / (distance * distance) to calculate the contribution from each pole, where distance is the Euclidean distance between the point and the pole.
displayField Function:
- Displays the magnetic field vector, including its direction and magnitude.
main Function:
- Defines a set of magnetic poles.
- Defines a point where the magnetic field is to be calculated.
- Calls calculateField to compute the magnetic field at the point.
- Displays the result using displayField.
