Unit -1. Electrostaitics
Electrostatics, the study of electromagnetic phenomena that occur when there are no moving charges—i.e., after a static equilibrium has been established. Charges reach their equilibrium positions rapidly, because the electric force is extremely strong.
Unit – 2. Electric current
An electric current is a flow of electric charge in a circuit. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit. The charge can be negatively charged electrons or positive charge carriers including protons, positive ions or holes.
Unit -3 Electric current of magnetic effect
The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.
unit 4 Magnetism and matter
Magnetic materials tend to point in the north-south direction. Like magnetic poles repel and unlike ones attract. Magnetic poles cannot be isolated i.e. always exists in pairs. Magnetic induction:- A magnet induces magnetism in a magnetic substance placed near it
