The correct Answer is:
To define magnetic field intensity, we need to evaluate the given options and identify the correct definition. Let's break this down step by step. ### Step 1: Understanding Magnetic Field Intensity Magnetic field intensity, often denoted as \( H \), is a measure of the strength of the magnetic field in a given area. It is defined in terms of the magnetic force acting on a unit magnetic pole. ### Step 2: Evaluating the Options We have four options to consider: - **Option A**: Magnetic moment per unit volume - **Option B**: Magnetic induction force acting on a unit magnetic pole - **Option C**: Number of lines of force per unit area - **Option D**: Number of lines of force crossing per unit volume ### Step 3: Analyzing Each Option - **Option A**: Magnetic moment per unit volume is not a definition of magnetic field intensity. This relates more to the magnetic properties of materials rather than the field itself. - **Option B**: Magnetic induction force acting on a unit magnetic pole is indeed the definition of magnetic field intensity. This option correctly describes how magnetic field intensity is quantified. - **Option C**: Number of lines of force per unit area refers to magnetic flux density (B), not magnetic field intensity. - **Option D**: Number of lines of force crossing per unit volume also pertains to magnetic flux density and does not define magnetic field intensity. ### Step 4: Conclusion Based on the analysis, the correct definition of magnetic field intensity is given in **Option B**: "Magnetic induction force acting on a unit magnetic pole." ### Final Answer **Magnetic field intensity is defined as the magnetic induction force acting on a unit magnetic pole.** ---
