10. How is magnetism related to moving charges discussed in Chapter 4 Physics Class 12?
Magnetism is intrinsically linked to moving charges. When electric charges move, they generate a magnetic field around them. This relationship is described by the Biot-Savart law and Ampere's circuital law. Additionally, a moving charge in a magnetic field experiences a force known as the Lorentz force, which is perpendicular to both the velocity of the charge and the magnetic field. This force is given by the equation F=q(v×B).
11. What is the most important topic of Class 12 Physics Chapter 4 NCERT Solutions?
One of the most important topics in Class 12 Physics Ch 4 NCERT Solutions is the concept of the Lorentz force and its applications. Understanding how moving charges interact with magnetic fields and how this interaction results in forces is crucial. This concept underpins the functioning of many electromagnetic devices, such as electric motors and particle accelerators.
12. What are the SI units for moving charges and magnetism NCERT Solutions?
Charge (q): The SI unit of electric charge is the Coulomb (C).
Magnetic Field (B): The SI unit of the magnetic field is the Tesla (T).
Current (I): The SI unit of electric current is the Ampere (A).
Force (F): The SI unit of force is the Newton (N).
13. What are the important topics in Moving Charges and Magnetism Class 12 NCERT Solutions?
Important topics in Ch 4 Physics Class 12 NCERT Solutions include:
The Lorentz force and its applications
Biot-Savart Law and Ampere's Circuital Law
Magnetic field due to a current-carrying conductor
Motion of charged particles in magnetic fields
Magnetic force on a current-carrying conductor
Torque on a current loop and magnetic dipole moment

14. What is the formula for a moving charge mentioned in Chapter 4 Physics Class 12 NCERT Solutions?
The force experienced by a moving charge in a magnetic field, known as the Lorentz force, is given by:
F=q(v×B)
where
F is the force,
q is the charge,
v is the velocity of the charge, and
B is the magnetic field.
15. What is a moving charge called according to Class 12 Physics Chapter 4 NCERT Solutions?
A moving charge is generally referred to as an electric current when the motion is steady. However, if referring to a single moving charge, it is simply called a "moving charge" or a "current-carrying charge." In a broader context, moving charges create an electric current, which is the flow of electric charge.
