Magnetism And Matter Class 12 Notes Chapter 5

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 its direction is from South pole to...

Moving Charges and Magnetism Class 12 Notes Chapter 4

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...

Current Electricity Class 12 Notes Chapter 3

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 charge and...

Electric Charges and Fields Class 12 Notes Chapter 1

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,...
