in many forms. Electric energy can be converted into useful work‚ or mechanical energy‚ by machines called electric motors. Electric motors work due to electromagnetic interactions: the interaction ofcurrent (the flow of electrons) and a magnetic field. Problem Find out how to make a simple electric motor.

Force Field Analysis Force field analysis is a management technique developed by Kurt Lewin‚ a pioneer in the field of social sciences‚ for diagnosing situations. It will be useful when looking at the variables involved in planning and implementing a change program and will undoubtedly be of use in team building projects‚when attempting to overcome resistance to change. Lewin assumes that in any situation there are both driving and restraining forces that influence any change that may occur. Driving

Introduction The purpose of this lab is to examine the motion of an electron‚ when it encounters a constant magnetic and electric field. We will also observe when the electric field and magnetic field will cancel each other out. This will lead to the electron having no net force acting upon it. By adjusting the values for the magnetic and electric fields‚ we will be able to check the different paths the electron follows. From this data we will be able to calculate the charge-to-mass ratio. Then

electric fields on the surface of the body. Here‚ the human body acts as a transmission medium supporting IEEE 802.3 half-duplex communication at 10Mbit/s. RED is used to convey the meaning of warmth in communication. Instead of relying on electromagnetic waves or light waves to carry data‚ a RedTacton transmitter couples with extremely weak electric fields on the surface of the body. The weak electric fields pass through the body to a RedTacton receiver‚ where the weak electric fields affect the

Have you ever encountered that a distinct and spectral whisper keeps revolving around you? Actually‚ this plot was presented in a movie called “Field of Dreams” which was filmed in 1989. In the movie‚ such an odd thing happened to a young man‚ Ray. What is more ridiculous is that Ray decided to follow the instructions given by the phantom voice‚ even though he was on the edge of bankruptcy‚ whereas most of us are afraid of pursuing or following our yearning hearts‚ eventually‚ there is no chance

and that is on the soccer field. I’ve been playing soccer since I could walk and it’s a passion that I’ll always have. As soon as I step onto the field‚ it’s like everything else around me disappears and nothing in the world matters except what happens on the field. Soccer is the only thing that keeps me sane. It clears my head of stress and worries‚ and gives me that extra push I need to get through a hard day or tough week. Being able to express my feelings at the field helps my emotions so much

involved with the ceramic Yttria Stabilized Zirconia (YSZ) by applying a DC electric field to the body during the sintering cycle. Data acquired from these experiments have shown a relation between the applied electric field and temperature‚ which cause densification to occur at lower temperatures and quicker times. Experiments conducted by Raj and others replicate flash sintering to understand how different electric fields and temperatures relate to each other by monitoring the shrinkage and densification
