Velocity selector class 11 |

In this lecture on PhysicsByDM, we explain the concept of a Velocity Selector in a clear, conceptual, and exam-focused manner according to the latest Class 12 Physics (Electromagnetism) syllabus. A velocity selector is an important device that uses mutually perpendicular electric and magnetic fields to allow only charged particles of a specific velocity to pass undeflected. This topic plays a key role in understanding charged particle motion, Lorentz force, and applications such as mass spectrometers. 🔹 Topics Covered in This Lecture: ✔ What is a Velocity Selector? ✔ Principle of Velocity Selector ✔ Arrangement of Electric and Magnetic Fields ✔ Force on a Charged Particle (Electric vs Magnetic) ✔ Condition for Zero Deflection (qE = qvB) ✔ Expression for Selected Velocity (v = E / B) ✔ Direction of Forces and Particle Motion ✔ Practical Applications of Velocity Selector ✔ Important Derivations & Exam Tips ✔ Diagram-Based Explanation 🎯 This Lecture is Helpful For: ✅ Class 12 Physics students ✅ FBISE / PECTAA ✅ Pre-Engineering students ✅ Pre-Medical students ✅ Board exams, MCQs & Entry Test preparation 📌 Watch till the end for strong concepts, derivations, and exam-oriented explanations. 👍 Like | 💬 Comment | 🔔 Subscribe to PhysicsByDM for complete Electromagnetism & Physics chapter-wise lectures. 🔖 Professional Hashtags for Maximum YouTube Reach: #VelocitySelector #Electromagnetism #Class12Physics #PhysicsByDM #CrossedFields #ElectricField #MagneticField #LorentzForce #ChargedParticleMotion #MassSpectrometer #FBISEPhysics #PECTAAPhysics #PreEngineering #PreMedical #BoardExams #EntryTestPreparation #PhysicsConcepts #PhysicsLectures #NumericalsPhysics #MCQsPhysics #LearnPhysics #OnlinePhysics #STEMEducation #PhysicsStudents #ConceptualPhysics #physics #newsyllabus #electrostatics #physicsbydm #measurement #education #physicstheory #physicalquantities #part1
