1. The focus of Ohm’s research was to study the conductivity of metals, and the behavior of electrical circuits.
2. Ohm discovered what is now known as the Ohm’s Law, which describes that “ If the temperature is constant, the current flow through the conductor is directly proportional to the potential difference and inversely proportional to the resistance.” He discovered this law mathematically, and published the law in his famous book called Die galvanische Kette, mathematisch bearbeitet (1827).
3. Ohm's later discovery was his acoustic law, which states that a musical sound is perceived by the ear as a set of a number of constituent pure harmonic tones. It is well known to be not quite true.
4. Ohm’s discoveries help us better understand electricity and conductivity, and help us with modern uses such as how to install electrical units in houses, and buildings.
How Electromagnetic Induction Works
How Electromagnetism Improves Our Lives
1) Electromagnetics controls, switches in relays, which help people use telephones and computers.
2) They are used in security systems for doors and windows in our homes and buildings.
3) Electromagnets are also found useful to NASA engineers that help create space crafts, which help us get to space.
4) Electromagnets are also used in transportation like airplanes, to help them fly, and also trains, that levitate the cars.
5) Electromagnets are even found in your back pocket. The strip on the back of a credit card contains magnet particles, that contain account information, thus making it easier to transfer that information.
Motors And Generators
when the device is used as a motor, a current is passed through the coil. The interaction of the magnetic field with the current causes the coil to spin. To use the device as a generator, the coil can be spun, inducing a current in the coil. The interior of the object on the left, is a perfect example of a motor.
So There You Have It....Electromagnetism Is Awesome!
