Electromagnetic force is a type of physical force created by the combination of electric and magnetic fields. It is one of the four fundamental forces of nature, along with gravitation, the weak force, and the strong force. It can be used to generate power, create images, and even control objects from a distance.
What is Electromagnetic Force?

Electromagnetic Force: A force that acts between particles that have an electric charge. It can attract or repel other particles with the same or opposite charge. Magnetic Field: A region of space around a magnet or an electric current where a magnetic force is exerted. Magnetic Flux: The total number of magnetic field lines that pass through a given area.

Electromagnetic forces can be used to levitate objects, such as a frog! The strength of the electromagnetic force is approximately 10⁴⁸ times that of gravity. The electromagnetic force is the third strongest of the four fundamental forces in nature. Stronger only than gravity. The electromagnetic force acts over the 2nd longest distance.
