Yes, larger black holes have stronger gravitational fields compared to smaller black holes. The gravitational force exerted by a black hole is directly related to its mass. According to Einstein's theory of general relativity, the curvature of spacetime around a massive object is determined by its mass and energy.
Black holes are incredibly dense objects with a tremendous amount of mass concentrated in a relatively small region. As a result, their gravitational pull becomes extremely powerful. The event horizon, which is the boundary beyond which nothing can escape the black hole's gravitational pull, is directly related to the mass of the black hole. The larger the mass, the larger the event horizon and the stronger the gravitational field.
In practical terms, this means that objects or particles near a larger black hole would experience a stronger gravitational force compared to those near a smaller black hole. For example, if you were to approach a supermassive black hole, like the one at the center of a galaxy, its gravitational pull would be significantly stronger compared to a stellar-mass black hole.
It's worth noting that gravity is a universal force, and the strength of the gravitational field depends not only on the mass of the black hole but also on the distance from its center. As you move closer to a black hole, the gravitational force becomes increasingly intense.
