NCERT Solutions for Class 12 Physics Chapter 4 Moving Charges And Magnetism


The space in the surroundings of a magnet or a current-carrying conductor in which its magnetic influence can be experienced is called a magnetic field. Here students will learn about magnetic fields and its reaction to charged particles, like electrons, protons, and wires carrying electricity. Students will also study how moving currents produce magnetic fields, and they will learn about Bohr’s model and other laws. Magnetism is a concept introduced in physics to help you understand one of the fundamental interactions in nature, the interaction between moving charges. Like the gravitational force and the electrostatic force, the magnetic force is an interaction at a distance. The direct derivations of topics like forces between two current-carrying wires, ampere circuital law are frequently asked in exams.
