Class 12 CBSE Physics Chapter: Magnetic Effects of Current as per the latest CBSE syllabus: Magnetic Effects of Current 1. Introduction Electric current produces a magnetic field. This magnetic field can exert a force on magnets and other current-carrying conductors. 2. Oersted’s Experiment Observation : When current flows through a wire, it deflects a nearby magnetic compass needle. Conclusion : A current-carrying conductor produces a magnetic field around it. 3. Magnetic Field Due to a Current (a) Magnetic Field due to a Straight Current-Carrying Conductor The field lines are concentric circles centered on the wire. Direction : Given by the Right-Hand Thumb Rule . Magnitude at a distance r from a long straight wire: B = μ 0 I 2 π r B = \frac{\mu_0 I}{2\pi r} Where: μ 0 = 4 π × 10 − 7   T \cdotp m/A \mu_0 = 4\pi \times 10^{-7} \, \text{T·m/A} (permeability of free space) I I = current, r r = radial distance (b) Magnetic Field due to a ...

Full notes on Class 12th Physics Chapter Current Electricity for CBSE Board: Chapter : Current Electricity 1 Introduction Electric current is the flow of electrons through a conductor. It is measured in amperes (A). 2 Electric Current Electric current is defined as the rate of flow of electric charge. Mathematically, it is represented as: I = Q/t where I is the electric current, Q is the electric charge, and t is the time. 3 Electric Circuit An electric circuit is a path through which electric current flows. It consists of a conductor, a switch, and a source of emf. 4 Ohm's Law Ohm's law states that the electric current flowing through a conductor is directly proportional to the potential difference across it, provided the temperature remains constant. Mathematically, it is represented as: V = IR where V is the potential difference, I is the electric current, and R is the resistance. 5 Resistance Resistance is the opposition to the flow of electric current. It depends on the le...
