Magnetic Field Due To Current Carrying Solenoid | Ch 19 ELECTROMAGNETISM | Physics 10 | Lecture 2 | National Book Foundation |Federal Board In this *Physics Class 10 Chapter 19 (Electromagnetism)* lecture from the *National Book Foundation (NBF)* and *Federal Board (FBISE)* syllabus, we explore how a *current-carrying solenoid* produces a *magnetic field* similar to that of a bar magnet. This lesson explains how the *magnetic field inside a solenoid is strong and uniform**, while outside it is **very weak**. Students will also learn to determine the **direction of magnetic field* using the **Right-Hand Rule for Solenoids**. A *solenoid* is a long, tightly wound coil of wire that generates a magnetic field when an electric current passes through it. The field from each loop combines to form a powerful and uniform magnetic field along its axis. This property makes solenoids fundamental in **electromagnets, electric motors, relays, and scientific instruments**. The lecture also explains how a *current-carrying solenoid behaves like a permanent bar magnet**, having distinct **north and south poles**. When brought near a magnet, it repels or attracts depending on the direction of current. Students will clearly understand how the **Right-Hand Grip Rule* determines the north pole of the solenoid — if you curl your fingers in the direction of current, your thumb points toward the solenoid’s **north pole**. 📚 Key Concepts: Definition of Solenoid Magnetic Field in Solenoid Direction of Magnetic Field (Right-Hand Rule) Solenoid as an Electromagnet Relation between Solenoid and Bar Magnet This topic builds a strong foundation for understanding **electromagnetism**, **electromagnetic induction**, and **applications of solenoids in electric devices**. 📌 Hashtags #MagneticField #Solenoid #Physics10 #Electromagnetism #RightHandRule #Electromagnet #FBISE #NBF #PhysicsLecture #CurrentCarryingSolenoid #MagneticPoles #PhysicsClass10 magnetic field due to current carrying solenoid, solenoid magnetic field class 10, physics 10 electromagnetism, right hand rule solenoid, solenoid as bar magnet, current carrying coil magnetic field, national book foundation physics class 10, federal board physics chapter 19, electromagnetism lecture class 10, solenoid north and south pole, working of solenoid, uniform magnetic field solenoid, ampere right hand rule, physics 10 ch 19 nbf fbise lecture 2
