To investigate magnetic fields using a compass, you can first observe the behavior of the compass needle when placed near different objects or materials. By noting the direction in which the needle points and how it reacts to various materials, you can determine the presence and strength of magnetic fields in the surrounding area.
You can also use a compass to map out the direction and intensity of magnetic fields by moving the compass around in a systematic manner and recording its readings at different locations. By analyzing this data, you can create a visual representation of the magnetic field lines and get a better understanding of the magnetic field's properties and characteristics in the area you are studying.
Overall, a compass can be a valuable tool for investigating magnetic fields as it provides a simple and straightforward way to detect and analyze magnetic phenomena.
Based on your observations in all the previous questions, explain in your own words how you can use a compass to investigate magnetic fields.
