Notes For All Chapters Physics Class 12 CBSE 1. The magnetic dipole moment of a magnetic dipole is given by M = m × 2I where, m is pole strength and 2I is dipole length directed from S to N. The SI unit of magnetic dipole moment is A-m2 or J/T. It is a vector quantity and […]

Notes For All Chapters Physics Class 12 CBSE 1. The space in the surroundings of a magnet or a current-carrying conductor in which its magnetic influence can be experienced is called magnetic field. Its SI unit is Tesla (T). 2. Oersted experimentally demonstrated that the current-carrying conductor produces magnetic field around it. When key K is closed, […]

Notes For All Chapters Physics Class 12 CBSE 1. The directed rate of flow of electric charge through any cross-section of a conductor is known as electric current. If ∆Q charge flows in time ∆t, then current at any time t is NOTE: Current is a scalar quantity. I is in the direction of flow of positive […]

Notes For All Chapters Physics Class 12 CBSE 1. Electrostatic Potential The electrostatic potential at any point in an electric field is equal to the amount of work done per unit positive test charge or in bringing the unit positive test charge from infinite to that point, against the electrostatic force without acceleration. NOTE: Electrostatic potential is […]

Notes For All Chapters Physics Class 12 CBSE 1. Electric Charge Charge is the property associated with matter due to which it produces and experiences electric and magnetic effect. 2. Conductors and Insulators Those substances which readily allow the passage of electricity through them are called conductors, e.g. metals, the earth and those substances which offer high […]
