Earth's magnetic field

forces in magnetic fields. This struck great interest and lead to further research. In the 1830’s, an English scientist named Michel Faraday was credited with the discovery of induced currents and the practical behind it. He first wrapped a copper wire around an iron ring. On one side of the ring, there was a battery with a switch. On the opposite side, there was a galvanometer. He noticed a strange pattern in variations in currents. This evolved into further experimentation with magnetic…

1. Existing Knowledge- Based on prior knowledge, the Sulfur and Iron powder can be separated by using a magnet. The known fact is that the Iron particles can be attracted to the Magnet because of the attraction of the opposite charges. The Magnet will pull and attract the Iron and leaving the Sulfur behind. The separation of Sulfur and Iron powder is successfully accomplished because of the property of attraction. Since Iron is a metal, it has a positive charge and one side of the magnet has a…

generators create electrical energy by creating a changing magnetic field. This works by moving a copper coil in a permanent magnetic field. The induced field created in the copper coil opposes the permanent one (according to Lenz's Law). These two opposing magnetic fields create the force that resists the rotation of the coils. When the light bulb is taken out no current can flow through the coil (Faraday's Law) so no opposing magnetic field is created. Hot Plate Why didn’t the power you…

are two field magnets on each side coil with wire. These two field magnets always have opposite polarity. On the middle of the motor there is an armature, two commutators and two brushes. When current flow though the two brushes, one of the brushes touches commutator plate 1 and the other brushes touches commutator plate 2. Then the armature A and armature B turn in to field magnets, because when the current flow though iron that coil with wire, it will produce a strong electromagnetic field.…

Magnetic therapy or magnet healing is a type of alternative medicine that have magnetic fields that generates healing powers towards a large number of diseases or conditions. These electromagnetic fields have been demonstrated to treat slow-healing fractures in the body and have shown good results towards to a few conditions. The website that has claimed to use this magnetic therapy are Skepdic.com. The claim that this complementary and alternative medicine practitioner is making goes…

completing the compass experiment and receiving successful results, we moved on to our last experiment of the unit. This experiment was called “Through it All.” During this experiment, students worked in small groups to test the strength of the magnetic force field through a variety of objects. Before breaking off into groups and performing the tests of each item, students were required to make a prediction about whether or not they thought a magnet could attract an object through each item…

Mechanical power is defined as torque and RPM (rotation per minute) and electric power is defined as current and voltage. Therefore, in order convert mechanical power into electric power, torque shall be converted into current and rpm shall be changed into voltage. The relation between the rpm and voltage can be defined with equations with the use of Equations. When there is a decrease in value in equations there is an increase in efficiency of power generator. In here, there is no loss when…

Every vehicle has a number of electrical instruments. Each one varies due to the certain make and model of the vehicle with the different variations on the particular vehicle. Take a truck for instant it has a speedometer, tachometer, and transmission temperature gauge. Due to the fact that it will be towing a heavy object and be putting stress on the motor, so it doesn’t get too hot the gauge is there to protect it. Now on a sport car your two main instruments will be the speedometer and the…

Diamagnetism can make levitation possible. How? Diamagnetic materials are repelled by magnetic fields. The most diamagnetic materials are graphite and bismuth. Technically, everything is diamagnetic but the force of it is very weak. Diamagnetism is present in everything, but is only observable if other types of magnetism, such as paramagnetism, ferromagnetism, ferrimagnetism, antiferromagnetism, etc. do not overwhelm it. Most of the time, diamagnetic materials’ effect is very weak. Levitating…

How Electro-mechanical Actuator Works? A Rotary Electromechanical Actuation system with an Electric Motor, a gear box & an elastic spring to absorb peak torque loads experienced during operational life. The Schematic below describes the system. Fig. 1.1 Rotary Electro-mechanical Actuator Gearbox Requirements: The Gear Box at the Motor Output is intended to amplify the torque output of the Motor with reduction in speed. The tentative ratio is set at 10:1. Functional Requirements of…
