A chemical bond is defined as the force of attraction between any two atoms in a molecule to maintain stability. Ionic bond: The chemical bond formed between two atoms by the transfer of one or more electrons from the atom of a metallic electropositive element to an atom of a non-metallic electronegative element. Covalent bond:

Electromagnet is a temporary strong magnet made from a piece of soft iron when current flows in the coil wound around it. It is an artificial magnet. The polarity and magnetic field strength can be changed. Demagnetized by switching off the current. Uses: lifting and transporting huge masses of iron scrap, loading furnaces with iron,
The space around the magnet where its influence can be experienced is known as the magnetic field. Magnetic Field Lines: The space around the magnet in which the compass needle rests in a direction other than the geographic north-south direction. Magnetism PDF Download PDF
The bodies which on rubbing acquire the property of attracting light bodies (such as paper pieces) are said to be electrified (or charged). If the acquired charge is not allowed to flow it is said to be static electricity. The study of properties of bodies electrified due to stationary charges is called electrostatics. Static Electricity
Solar energy: – from the sun – used in solar cookers, solar water heaters – by use of solar photovoltaic cells (solar cells) Wind energy: – K.E of wind converted to electrical energy by windmills – used to run flour mill, water lifting pump Tidal energy: – from rising and falling ocean waves……… More about
