Summary:This article presents an analytical model of a harvested power from a Magnetostrictive Euler-Bernoulli cantilevered beam. Most of the cantilevered beam harvesters used a base excitation system to harvest energy. In contrast, this analytical model predicts the displacement and generated power in a cantilevered beam harvester with a fixed base. Furthermore, the effects of internal and external damping are considered. The magnetostrictive material in this harvester is permendur. In comparison to piezoelectric materials and Terfenol-D, permendur has less vulnerability to shock forces and is machinable. This paper reports a mechanical modeling of Euler-Bernoulli beam and a magneto-mechanical model of permendur to find the generated voltage and power of the harvester. Moreover, the analytical model has been experimentally validated. Experiment result shows the generated voltage is \pmb{1400\ \mu}\mathbf{V} and power density is 2.72 W/m 3 *
