    Introduction Larmor precession is a phenomenon observed in quantum mechanics, where the spin (or magnetic moment) of a particle precesses around an external magnetic field. This principle is fundamental to technologies like magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) spectroscopy. Basic Principle of Larmor Precession A magnetic moment in an external magnetic field…

    Introduction Torque, also known as moment or moment of force, is a measure of the force that can cause an object to rotate around an axis. Torque is a vector quantity, meaning it has both magnitude and direction. Definition and Formula The torque due to a force acting at a point with position vector relative…

    24.1 Introduction to Torque and Equilibrium In this chapter, we will explore the concepts of torque and equilibrium. Torque is a measure of the force required to cause an object to rotate, while equilibrium is the state in which the net force and net torque on an object are both zero. These concepts are crucial…

    23.1 Introduction to Rotational Motion In this chapter, we will explore inertia and angular momentum, two fundamental concepts in rotational motion. These concepts are essential for understanding how objects rotate, conserve angular momentum, and how external forces can change an object’s rotational motion. 23.2 Inertia Inertia is the inherent property of an object that resists…
