The simulations were accomplished using Finite Difference Time Domain Simulator (FDTD Simulator) based on the Finite Difference Time Domain Method. FDTD Simulator is sophisticated simulator and can take a significant amount of time to learn the complex features and it can run on a variety of operating systems. The primary advantage of FDTD over other full-wave models is that‚ FDTD being a time domain method allows broadband analysis of the antenna by Gaussian pulse excitation. The antenna characteristics

design for Portable Charger‚ however we are trying to promote our inductor to be used in the input IC charger as well. With the usage of the inductor in input‚ charging time of the battery can be improved. Our inductor is also able to sustain the magnetic field from the current flowing through providing extra energy capacity and stability in current discharge. Usage for inductor in P.Charger - Based on teardown for Romoss powerbank design‚ there are 2 area that our inductors can be used. 1) Output

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).

object within a straight line‚ then the forces will reinforce or cancel one another depending of factors such as magnitude and direction. Unbalanced forces will cause changes in the direction or speed of an object. Electromagnetism is composed of magnetic fields and electric currents. The electromagnetic spectrum is mediated by a particle called photon. Example: heat‚ visible light‚ radio waves‚ X-rays‚ UV radiation.

push pins. I curled the magnet wire around the battery so that it was in a coil shape‚ then pulled the ends out so that it had tails. Then‚ I used sandpaper to manipulate the clear coating on the ends of the magnetic wire. The paperclips were bent so that they supported the tails of the magnetic wire‚ or “armature arms”. I had to use small pliers‚ an extra material‚ to accomplish this. I used an old textbook as a support base to conduct the rest of the experiment with. The paperclip stands were fastened

experiment which showed that there was a connection between electricity and magnetism. * When a current was switched on through a wire‚ it made a compass needle turn so that it was at right angles to the wire. * The current had produced a magnetic field strong enough to cause the compass needle to turn. Additional effects due to experiment * It was already known that an electric current in a wire has a heating effect‚ and may cause the wire to glow. This showed that the three phenomena
