The correct Answer is:
To solve the question, we need to identify the correct term that describes the line on the Earth's surface where the magnetic field is horizontal. Let's break this down step by step: ### Step 1: Understand the question The question asks for the line on the Earth's surface that connects points where the magnetic field is horizontal. ### Step 2: Analyze the options We have four options: 1. Magnetic meridian 2. Magnetic axis 3. Magnetic equator 4. Magnetic line ### Step 3: Define the terms - **Magnetic meridian**: This is a vertical plane that contains the magnetic field lines and the direction of the magnetic field at a given location. - **Magnetic axis**: This refers to the line that runs from the magnetic north pole to the magnetic south pole. - **Magnetic equator**: This is the line on the Earth's surface where the magnetic field is horizontal. It divides the magnetic field into two hemispheres. - **Magnetic line**: This term is not commonly used in the context of Earth's magnetic field. ### Step 4: Identify the correct answer From the definitions, the term that specifically refers to the line where the magnetic field is horizontal is the **magnetic equator**. ### Conclusion Thus, the line on the Earth's surface joining the points where the magnetic field is horizontal is the **magnetic equator**. ### Final Answer The correct answer is **Magnetic Equator**. ---
