ELECTRICITY AND MAGNETISM

• Electricity - Is a natural phenomenon that occurs throughout nature and takes many different forms
• Electricity - Is briefly defined as the flow of electric charge
• Electricity - Is described as the passage of electric charge inside a device
• 2 TYPES OF ELECTRICITY:

  1. Static Electricity
  2. Current Electricity
• Static Electricity - Friction is created by rubbing or contacting two or several items together
• Static Electricity - has charge but does not move or flow
• Current Electricity - the movement of electrical charge via conductor throughout an electrical field produces a voltage
• Current Electricity - The rate of flow of electrons
• Current Electricity - It is produced by moving electrons and it is measured in amperes
• Magnetism - Is defined as an attractive and repulsive phenomenon produced by a moving electric charge
• Magnetism - Unlike poles attract and like poles repel
• Thales of Miletus - Greek philosopher ans cientist
• Thales of Miletus - He discovered static electricity
• Benjamin Franklin - American inventor who was famous for his kite experiment and lightning rod
• Charles-Augustin De Coulomb - French physicist and engineer
• Charles-Augustin De Coulomb - Invented torsion balance
• Coulomb's Law - describe the electrostatic interaction between charged particles
• Coulomb's Law - state that electrostatic force between charge particles is directly proportional to the product of the charges and inversely proportional to the square of the distance between them
• 2 TYPES OF ELECTROSTATIC FORCE:

  1. Attractive Force
  2. Repulsive Force
• Coulomb's Law - The higher the value of charge; the higher the electrostatic force
• Coulomb's Law - The further the distance between charges, the lower the value of electrostatic force
• Coulomb's Law - The closer the charge, the higher the electrostatic force
• Hans Christian Oersted - Danish physicist and chemist
• Hans Christian Oersted - He discovered electromagnetism in 1820
• Andrei-Marie Ampere - French physicist and mathematician
• Andrei-Marie Ampere - credited for establishing the basis of electrodynamics
• Michael Faraday - English physicist and inventor
• Michael Faraday - first to discover the principles of electromagnetism induction in 1831
• Ampere's Law - magnetic fields are related to the electric current produced in them.
• Ampere's Law - The law specifies the magnetic field that is associated with a given current or vice-versa, provided that the electric field doesn’t change with time.
• Ampere's Law - “The magnetic field created by an electric current is proportional to the size of that electric current with a constant of proportionally equal to the permeability of free space.”
• Hans Christian Oersted - Danish physicist and chemist.
• Hans Christian Oersted - discovered the relationship between electricity and magnetism in 1820.
• Andrei-Marie Ampere - French physicist and mathematician.
• Andrei-Marie Ampere - Credited for establishing the basis of electrodynamics.
• Michael Faraday - English physicist and inventor.
• Michael Faraday - First to discover the principles of electromagnetic induction in 1831.
• Faraday's Law - is also known as electromagnetic induction
• Faraday's Law - This phenomenon is known as electromagnetic induction.
• Faraday's 1st Law - describes the induction of emf in a conductor
