Q: What is the magnetic field due to a magnetic dipole at a point along its axial line?
Solution: The magnetic field due to a magnetic dipole at a point along its axial line is given by B = (μ₀/4π) * (2m/r³).
Steps: 5
Step 1: Understand what a magnetic dipole is. A magnetic dipole consists of two equal and opposite magnetic charges separated by a small distance.
Step 2: Identify the point where you want to calculate the magnetic field. This point is along the axial line of the dipole, which is the line that extends outwards from the center of the dipole.
Step 3: Know the formula for the magnetic field (B) due to a magnetic dipole at a point along its axial line. The formula is B = (μ₀/4π) * (2m/r³), where μ₀ is the permeability of free space, m is the magnetic moment of the dipole, and r is the distance from the center of the dipole to the point.
Step 4: Plug in the values for μ₀, m, and r into the formula to calculate the magnetic field at that point.
Step 5: Simplify the expression to find the value of the magnetic field B.
