# NCERT Solutions for Class 12 Physics Chapter 4 Moving Charges and Magnetism

### Let us start reading the preparation article Regarding CBSE 12 Class

NCERT solutions for class 12 Physics chapter 4 Moving charges and magnetism: In the first and second chapter of NCERT class 12 physics you have studied about charge under rest, then in the second chapter you studied that the rate of change of charge with respect to time is current. Now in NCERT solutions for class 12 Physics chapter 4 Moving charges and magnetism. you will study that a charge moving in a magnetic field with a velocity v can produce a force. And a current carrying conductor in a uniform magnetic field will experience a force. Using these principles there are certain equipment and measuring devices. Try to find it out yourself. Here you are provided with NCERT solutions for class 12 Physics chapter 4 Moving charges and magnetism.

The main two laws discussed in the NCERT grade 12 chapter 4 are Biort-savart law and Amperes circuital law. Based on these laws there are many problems and derivations in NCERT solutions for class 12 Physics chapter 4 Moving charges and magnetism. Go through all the derivation and problems based on these laws.
