Electromagnetic waves are an essential aspect of the study of physics, particularly in the realm of electromagnetism. These waves are characterized by their ability to propagate through space without the need for a medium, unlike mechanical waves such as sound waves. At the heart of electromagnetic theory lies the groundbreaking work of James Clerk Maxwell, who formulated a set of equations that unified the phenomena of electricity and magnetism.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

3. Electricity and magnetism are different facets of
Electromagnetism.
Introduction
• A moving electric charge produces magnetic field.
• Changing magnetic fields move electric charges
This connection first elucidated by Faraday, Maxwell.
Einstein saw electricity and magnetism as frame
dependent facets of unified Electromagnetic force.
4. Magnetic field lines
The magnets exert their influence in the surroundings, this is called
magnet field.
Magnetic field is a quantity that has both direction and magnitude.
The direction of the magnetic field is taken to be the direction in
which a north pole of the compass needle moves inside it.
5. Direction of Magnetic field
(1) Right hand-palm rule :
“First make the thumb and fingers of the right hand
perpendicular to each other and put the thumb along the wire in
the direction of the current and fingers point towards the point
of observation.”
6. (2) Right hand-thumb rule :
“If the thumb is along the direction of current,
wrapped fingers will show the direction of circular
magnetic field lines.”
7. (3) Fleming Left-hand rule :
“Hold out your left hand with forefinger, second finger and
thumb at right angle to one another. If the fore finger
represents the direction of the field and the second finger that
of the current, then thumb gives the direction of the force.”
8. (4) Right hand rule :
“Hold out the right hand with the first finger, second and
thumb at right angle to each other. If finger represent the
direction of the line of force, the thumb points in the direction
of motion or applied force, then second finger point in the
direction of the induced current.”
9. (5) Magnetic field in a circular loop :
Clockwise : South pole Anticlockwise : North pole
10. Electromagnet
Arranging wire in coil and running a current through
produces a magnetic field that looks a lot like bar
magnet.
• Called an electromagnet
• Putting a real magnet inside, can shove the magnet back and
forth depending on current direction : Solenoid
11. Tesla Coil
A Tesla coil is a resonant air core transformer system
inventor Nikola Tesla in the 1890’s.
Originally, Tesla coils were designed to broadcast electricity
and signals wirelessly.
It is a from of induction coil for producing highfrequency
alternating currents.
12. The Electromagnetic Spectrum
Relationship between frequency, speed and wavelength,
frequency × wavelength =speed of light
Different frequencies of electromagnet radiation are better
suited to different purposes.
The frequency of a radio wave determines its propagation
characteristics through various media.
Photon energy is directly proportional to the wave frequency,
so gamma ray photons have very low energy.
13. ELF-EMF may affect the DNA in Human cells
Used technical to detect any DNA damage at the level of the
individual eukaryotic cell (Comet assay).
Human primary fibroblast cells were exposed to 50Hz of emf at 1
militesla (mT) of flux density.
Assay showed that the processes of DNA replication and cell
reproduction were the ones affected, not on the
DNA it self.
In conclusion, the exposure of human primary fibroblast to
ELF-EMF simulates cell termination (necrosis) rather than
DNA alteration (Focke et al. 2009)
