Magnetic Field due to a Straight Current-carrying Conductor:
The magnetic field lines around a straight conductor carrying a current are concentric circles. The direction of a magnetic field is given by the Right-Hand Thumb Rule.Take a magnetic needle pivoted at its centre and free to move in horizontal plane.
Take a thick and insulated copper wire PQ and connect it to the battery circuit through a key K and a variable resistance Rh.
Hold the wire PQ parallel and just above the axle of the magnetic needle and press the key. It is observed that N-pole of the needle points towards the west so long the current continues to flow through the wire. It is also observed that if the current is increased or decreased, the deflection of the magnetic needle also increases or decreases.
If the direction of the current through PQ is reversed, i.e., if the current flows from Q to P, then N-pole of the needle is deflected towards east, this experiment shows that a magnetic field is set up around a current carrying conductor.

Visible movements are the type of movements that can easily be perceived by the naked eyes. These movements include activities such as walking or running, one can easily see that movement.
Invisible movements, on the other hand, are the types of movements that are not perceivable by the naked eye. The movements are so minute that without the aid of special instruments, they cannot be seen. The examples include; movements caused by pulsating blood in the body and the vibration of atoms in a solid matter.

Double Displacement Reaction:Reactions in which ions are exchanged between two reactants forming new compounds are called double displacement reactions.
<i>AB + CD → AC + BD</i>
Example: When solution of barium chloride reacts with the solution of sodium sulphate, white precipitate of barium sulphate is formed along with sodium chloride.
<i>BaCl2 + Na2SO4 → BaSO4 + 2NaCl</i>

CFC stands for Chlorofluorocarbon. As the name suggests, it consists of chlorine, fluorine, and carbon. They are mainly used as refrigerants in cooling systems. As it is released in the atmosphere, it reacts with light and produces the chlorine (Cl-) radical. This chlorine radical, catalyzes the Ozone (O3) present in the atmosphere, and breaks down ozone into oxygen molecule. Hence, ozone depletion occurs.
