Learning Objectives
- Understand the concept of Magnetic Field due to Electric Current and apply the right-hand thumb rule to determine the direction of the magnetic field around current-carrying conductors, including straight wires and circular loops.
- Describe and illustrate Magnetic Field Lines, their properties, and how they represent the strength and direction of magnetic fields.
- Calculate the Force on a Current-Carrying Conductor in a magnetic field and use Fleming's left-hand rule to determine the direction of the force.
- Analyze the magnetic field patterns produced by Electromagnetism in Circular Loops and Solenoids, and explain the uniformity of the magnetic field inside a solenoid.
- Identify the components and safety measures in Domestic Electric Circuits, including the function of live, neutral, and earth wires, and the role of fuses.
- Explore the deflection of a compass needle near magnets and current-carrying wires, and understand Compass Needle and Magnetic Effect of Current through Oersted’s observation.
- Explain the formation and applications of an Electromagnet and Its Use, using a current-carrying solenoid with a soft iron core, and compare it with a bar magnet.
