To derive the expression for the magnetic field at a point on the axis of a magnetic dipole, we will follow these steps: ### Step 1: Define the Magnetic Dipole A magnetic dipole consists of two equal and opposite magnetic charges (or poles) separated by a distance \(2l\). The magnetic moment \(M\) of the dipole is defined as: \[ M = m \cdot 2l \] where \(m\) is the pole strength. ...
