The paper presents a novel solution describing magnetized spacetime outside an electrically charged object with NUT parameter. The solution is obtained by applying Ernst magnetization to the Reissner-Nordstrom-Taub-NUT spacetime as a seed. After discussing some physical aspects, it is shown that the extremal entropy of a magnetized Reissner-Nordstrom-Taub-NUT black hole can be reproduced using the Cardy formula.
We present a novel solution describing magnetized spacetime outside an electrically charged massive object equipped with NUT parameter. To get the solution, we employ the Ernst magnetization to the Reissner-Nordstrom-Taub-NUT spacetime as the seed. After discussing some physical aspects of the spacetime, we show that the extremal entropy of a magnetized Reissner-Nordstrom-Taub-NUT black hole can be reproduced by using the Cardy formula.
