microwaves‚ remote control cars‚ and it creates energy cleanly and fast. One of the most important uses for electromagnetism is in electronic motors. The main components are a core rod and many copper wires coiling around the iron rod. The coils rotate around the iron rod because of the magnetic force caused by a certain magnetic field on an electric current. While doing so‚ this turns electrical energy into mechanical energy. When this happens‚ normally a gear is attached to the end of the rod. That

Faraday’s Law of Electromagnetic induction where whenever a conductor cuts magnetic flux‚ dynamically induced electromotive force is produced‚ and this causes current to flow if the conductor/conductors is closed. The direction of induced current is given by Fleming’s right hand rule. A DC generator consists of these vital parts: o Yoke- It is the outer frame of a DC and it is made up of cast iron or steel. It carries the magnetic flux produced by field

of Magnets Objects having magnetic field is called as magnets. Normally magnets are of two types- Permanent magnets and Electro magnets. Permanent magnets are those magnets which occur in nature and do not depend upon external source for their magnetic field. On the other hand electromagnets are those magnets which use electric current to generate magnetic field. Classification of Magnets There are different types of magnets with different physical and magnetic properties and strength. These

Investigatory Projects in Physics Repulsorlifts as a Method of Stable Magnetic Levitation | Repulsorlifts were used in the study to find out if they can be used to replace the wheels of a conventional car. It was hypothesized that it will be able to lift a car using magnetic repulsion forces. The different magnets were tested individually with the usual tests for magnetic strength‚ size‚ and temperature increase‚ which were done in the preliminary testing. The prototype road and car were then constructed

Project #15: Make Homemade Glue from Milk With milk‚ white vinegar and baking soda‚ you can make your own glue right at home. Make it an investigatory project by changing up the recipe and testing which results in the strongest glue. You could also try varying the ingredients to make it dry faster‚ or work on different materials (wood vs. plastic vs. paper).

Byrd 1 Wesleigh Byrd Mr. Holloway Composition 11 8 March 2013 At the “Core” of Technology ! Traveling backwards along the timeline of how technology has impacted the day-to-day responsibilities of life can seem archaic to most. For quite a few years offices thought of the fax machine as the most expeditious way of transferring information‚ namely documents. This process of “sending” information often created frustrating scenarios resulting in a loss of time. A fax machine would have

Required: * An iron nail (around 8 cm) * A copper wire (15 cm) * Vernier Logger Pro * Magnetic Field sensor * Battery * Switch * Sand Paper Background Theory: Some metals such as nickel and iron can be magnetised using an electromagnet. The strength of the electromagnet depends on various factors which include the current‚ no. of turns per unit length and the core of the magnetised metal. In this experiment‚ I will study the effect of spacing between the turns of
