Einstein showed that, the effect of gravitational field on a space-time is explained mathematically using Ricci tensor. Also, it is clear that the effect of electromagnetic filed on a space-time is explained with electromagnetic tensor which satisfies Maxwell's equations. In real physics world, both electromagnetic and gravitational fields exist in a space-time simultaneously. So, the space-time should be considered, simultaneously using two second rank tensors. In this manuscript, a new approach for writing a general field equation for both gravitation and electromagnetism in a four dimensional space-time is proposed. As a result, a relationship between electromagnetism and gravitation is obtained.
