  • DEFINING DIAMAGNETISM

    DEFINING DIAMAGNETISM
    Although, he may not be the first to discover the theory of diamagnetism, he definitely had a heavy influence on uncovering the knowledge we now know today.
    Diamagnetism is the weak physical phenomenon in the magnetic field that creates materials to repel from the magnetic force. An example, if you hold a magnet to vile of water, the water will naturally move away from the magnetic force.
  • TYNDALL INFLUENCE ON DIAMAGNETISM

    Testing his theories on crystals, he discovered the 'line of elective polarity'. This means that the fiber structure of the crystal has a great influence on the direction in which magnetism flows. ‘anything that affects the mechanical arrangement of the particles will affect…the line of elective polarity’ and in crystals or other substances where there are several different ‘lines of elective polarity’ of different strengths the actual behavior of a piece of matter will be complex.
  • WHY IS THE SKY BLUE

    TYNDALL EFFECT (CONT.) The blue color of the sky was originally attributed by
    scientists to the Tyndall effect. This effect is a preferential scattering of shorter wavelength of blue light by particulate matter in the atmosphere. More scattering of blue light is by the increased amount of particles in the air closer to the earth is given as the reason.
