ELECTROMAGNETIC INDUCTION Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. It is described mathematically by Faraday’s law of induction‚ named after Michael Faraday who is generally credited with the discovery of induction in 1831. Electromagnetic induction was discovered independently by Michael Faraday and Joseph Henry in 1831; however‚ Faraday was the first to publish the results of his experiments.[4][5] In

Induction Current is produced in a conductor when it is moved through a magnetic field because the magnetic lines of force are applying a force on the free electrons in the conductor and causing them to move. This process of generating current in a conductor by placing the conductor in a changing magnetic field is called induction. This is called induction because there is no physical connection between the conductor and the magnet. The current is said to be induced in the conductor by the magnetic

What is electromagnetic radiation? Electromagnetic energy is a term used to describe all the different kinds of energies released into space by stars such as the Sun. These kinds of energies include some that you will recognize and some that will sound strange. They include: * Radio Waves * TV waves * Radar waves * Heat (infrared radiation) * Light * Ultraviolet Light (This is what causes Sunburns) * X-rays (Just like the kind you get at the doctor’s office) * Short waves

Hume’s Problem Of Induction In A Treatise of Human Nature‚ Hume challenges the traditional theories of causality‚ the idea that one can make an observation about two events and infer a new claim concerning the conjunction of the first event and the “resulting” second event. Instead of accepting this notion of causality‚ Hume questions the certainty of matters of fact and more specifically induction. Hume states there are two distinct types of knowledge: relations of ideas and matters of fact

Murakami 10D SHOULD WE USE ELECTROMAGNETIC WAVES FOR MEDICAL PURPOSES? In terms of definition‚ Electromagnetic Wave is a “non-particulate radiation (radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge)”. Thus‚ in simpler words‚ electromagnetic is a transmission of energy‚ caused by the oscillation and of electric and magnetic fields. The word electromagnetic wave or electromagnetic radiation may sound complex

The electromagnetic spectrum is made up of six different types of waves. Radio waves‚ Microwaves‚ Infrared waves‚ Visible light‚ Ultraviolet light‚ X-rays and Gamma rays. The radio waves are used to transmit radio and television signals. The infrared waves are used to tell temperature of areas. Visible light is all the colors that we can see. Ultraviolet light can help things grow but to much can cause diseases such as skin cancer. X-rays are used as a tool to find broken bones or take pitchers

The Figure 6-18 in my text book was an example of an electromagnetic spectrum‚ which is all wavelengths of light both seen and unseen (Trefil & Hazen‚ 2010). The display of the electromagnetic spectrum showed gamma rays‚ X-rays‚ ultraviolet light‚ infrared‚ visible light‚ microwave‚ radio waves‚ as well as a visible spectrum wavelength (Trefil & Hazen‚ 2010). The diagram shows at what frequency and wavelength each wave moves and what it allows us to see‚ hear‚ and feel with visible light

Electromagnetic Waves It was once the great Scottish physicist James Clerk Maxwell (1831-1879) who had presented that electric and magnetic fields unstable together can form a spreading wave‚ appropriately called an electromagnetic wave. The properties of an electromagnetic wave are as follows: 1. They can travel through a vacuum at the same high speed‚ which is much faster than other types of waves that travel through a material. 2. They show the normal wave properties of reflection‚ refraction

Radios and microwaves both use radiation from the electromagnetic spectrum Visible light can be split into a spectrum of colours .. from red through the rainbow colours to violet but visible light is just a small part of the whole electromagnetic spectrum All the different types of electromagnetic waves travel at the same speed through a vacum .. the waves can be orderd by wave length remebered that waves with the shortest wave lengths have the highest frequency and the most energy and the waves
