A non-singular magnetic black hole in nonlinear electrodynamics has been introduced recently whose Lagrangian contains an exponential factor [15]. We show that such regular black holes are available without resorting to a transcendental factor. A much simpler example of regular magnetic black hole solution is presented which admits the Schwarzschild limit as well as the unconditional unitarily condition.
