To use a compass to investigate a magnetic field, you would first need to observe how the needle of the compass behaves when it is in close proximity to the source of the magnetic field.
If the needle of the compass aligns with the direction of the magnetic field lines, it indicates that the magnetic field is strong in that area.
On the other hand, if the needle of the compass does not align with the direction of the magnetic field lines, it could indicate that the magnetic field is weaker in that area or that there are other forces at play influencing the compass needle.
By moving the compass around the area and noting the behavior of the needle, you can map out the strength and direction of the magnetic field in that location. This can help provide valuable information about the size and shape of the magnetic field as well as any anomalies or disturbances present in the area.
Based on your observation in the previous question explain in your own words how you can use a compass to investigate a magnetic field
