To find the expression for the magnetic flux density \( B \) at a point in the end-on position (or axial position) of a magnetic dipole, we can follow these steps: ### Step 1: Understand the Setup We have a bar magnet with a length of \( 2L \). The north pole is at one end and the south pole is at the other end. We want to find the magnetic flux density at a point \( P \) located along the axis of the magnet at a distance \( R \) from the center of the magnet. ### Step 2: Define the Magnetic Dipole Moment The magnetic dipole moment \( m \) of the bar magnet is defined as: \[ ...
