Relativistic jets from several kinds of objects in the universe have been found. It is believed that they are all formed by violent phenomena near the black holes. Among the proposed mechanisms, the magnetic mechanism of the jet formation is becoming most promising because it may explain not only the acceleration but also the collimation of the jets. However, the distinct mechanism has not yet been shown. Here we report a numerical result of relativistic jet formation driven by magnetic field due to a current loop near a rapidly rotating black hole. Beside the current loop, there are magnetic flux tubes that bridge the region between the ergosphere and the rotating disk, which is called 'magnetic bridge'. The numerical result shows that the magnetic bridge is not stationary and expands explosively to form a relativistic jet when the black hole rotates rapidly.
