Magnetic, electrostatic and gravitational forces come under the category of :

Forces are categorized based on whether physical interaction is required between objects. Contact forces, such as friction and muscular force, require objects to be physically touching [5]. In contrast, non-contact forces act at a distance through fields without any physical contact [2]. Magnetic force is a non-contact force because a magnet can exert a push or pull on magnetic materials from a distance [2]. Similarly, electrostatic force is exerted by a charged body on another charged or uncharged body without touching [4]. Gravitational force is the attractive force the Earth exerts on objects, pulling them toward its center without physical contact, thus classifying it as a non-contact force [3]. Therefore, magnetic, electrostatic, and gravitational forces all fall under the category of non-contact forces [1].
