A magnetic field acts on objects with magnetic properties, such as iron or steel. A gravitational field acts on all objects with mass, regardless of their composition. An electric field acts on objects with electric charge, either positive or negative. **

An electric field is created by electric charges and exerts a force on other charges. A magnetic field is created by moving electric charges and exerts a force on other moving charges. A gravitational field is created by mass and exerts a force on other masses. While all three fields are fundamental forces in nature, they have different sources and effects on objects within their influence. **

A gravitational field is a region in which a mass experiences a force due to gravity, while an electric field is a region in which a charged particle experiences a force due to an electric field. A magnetic field is a region in which a moving charged particle experiences a force due to a magnetic field. The key difference between these fields is the type of force they produce and the type of particles that interact with them. Gravity affects all masses, electric fields affect charged particles, and magnetic fields affect moving charged particles. **
