SUMMARY
The force in the z-direction on the gyrocenter of a charged particle in a diverging magnetic field can be determined using the equation \(\vec{F} = -\mu_m \vec{\nabla}B\). This relationship indicates that the effective force is influenced by the magnetic field gradient, \(\frac{\partial B}{\partial z} < 0\). The sign of the force is contingent upon the charge of the particle, as derived from the Lorentz force applied to the guiding center. Understanding this relationship is crucial for analyzing particle dynamics in non-uniform magnetic fields.
