## Abstract

In this paper, thermodynamics and phase transition are investigated for the regular Bardeen black hole. Considering the metric of the Bardeen spacetime, we derived the Unruh-Verlinde temperature. Using the first law of thermodynamics, we derived the expression of the specific heat and plot its behavior. It results that the magnetic monopole charge $\beta$ reduces the temperature and induces a thermodynamics phase transition in the spacetime. Moreover, when increasing $\beta$, the transition point moves to higher entropy.
