Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Electromagnetism is a fundamental force that acts between
A
particles with positive or negative charges
B
all particles
C
protons only
D
neutrons only
Explanation: 

Detailed explanation-1: -The electromagnetic force, also called the Lorentz force, acts between charged particles, like negatively charged electrons and positively charged protons. Opposite charges attract one another, while like charges repel. The greater the charge, the greater the force.

Detailed explanation-2: -Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B.

Detailed explanation-3: -Electromagnetism is a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles. The electromagnetic force is one of the four fundamental forces and exhibits electromagnetic fields such as magnetic fields, electric fields, and light.

Detailed explanation-4: -It is the fundamental interaction that binds electrons to nuclei to form atoms and binds atoms together in molecules and solids. The electric force, an aspect of the electromagnetic force, is either attractive or repulsive depending on whether the charges involved are positive (+) or negative(-).
