No, objects do not have to be touching each other to exert electrical force. The force between charged objects can be exerted through electric fields, which can act over a distance. This force diminishes with distance according to Coulomb's Law.

Some forces that act on objects without touching them include gravitational force, magnetic force, and electric force. These forces can exert a push or pull on objects even when they are not in direct contact with them.
Objects that do not touch can still exert a force on each other through fields such as gravitational, electrical, or magnetic fields. These fields create a force that can act at a distance without physical contact between the objects.
When two objects have opposite electrical charges, they exert an attractive force on each other. This force is known as the electrostatic force. Oppositely charged objects will be pulled towards each other until they come into contact or the force is balanced by another force.
Objects can exert forces on each other without touching through fields, such as gravitational, electric, and magnetic fields. Gravity, for example, causes the Earth to exert a force on the Moon, keeping it in orbit. Similarly, magnets can attract or repel each other without being in physical contact.
Yes, a magnetic force is a noncontact force because it can act on an object without physically touching it. Magnetic fields can exert forces on objects that have magnetic properties.
