Özet

In this paper, we study the radial and angular tidal forces in the vicinity of rotating ModMax black hole. The radial tidal forces intensify with an increase in charge but diminish as the ModMax parameter, gamma, increases. Consequently, the angular tidal forces become less effective as the charge increases and become substantially stronger as the gamma parameter increases. Furthermore, we analyze the behavior of the geodesic deviation vectors eta(1 )and eta(& icirc;) in the radial and angular direction, respectively. Increasing the magnitude of charge causes the radial geodesic deviation vector eta(1) to move toward the center of the black hole. In contrast, the deviation increases as the value of the spin parameter increases. The radial geodesic deviation vector compresses to certain range before stretching continuously, as the values of radial coordinate r and gamma grow rapidly.
