The science experiment that my partner and I are going to test is, do different brands of batteries affect the electric current of an electromagnet? Electromagnets are magnets that can be powered on and off, they can do simple tasks such as ring doorbells to surgically pull a steel splinter from your eye (Stringer). There are many factors that may affect the way electricity flows throughout metals. For example, the number of coils wrapped around the metal object may affect its magnetic strength.…
mass, momentum and energy.The magnetohydrodynamic phenomena are a consequence of the mutual interaction of the fluid flow and the magnetic field. As is well known, a conductor crossing magnetic field lines gives rise to an induced electric field, which causes an electric current in the conducting fluid. The following are the Maxwell,s equations ∇⋅D = ρcf ∇⋅B = 0 ∇×E = −∂B ∂t ∇×H = J f + ∂D ∂t…
travel much more slowly. So how does the current come on everywhere as soon as the switch is closed? It is because the free electrons are already spread throughout the wire. As soon as the switch is closed, there is a force on all electrons (i.e. electric potential difference) which causes them to move (“Physics 16-18”, 2017). 1 Why do the ends of the battery get hot after the wire touches them for an extended period of time? Electrons traveling through the wire, coiled around an iron nail cause…
What is a circuit? How do they work? An electric circuit is a kind of path made up of wires that allows the flow of electrons. The circuit has to be made in a circular form, as the electrons must frequently move in a full loop, in which they will return to their original position and then complete the loop again. (“What is an electric circuit?”) The battery or another source of power provides the voltage, or ‘electrical push’, that makes the electrons move through the circuit. When the electrons…
and how it works. One should also understand that electricity is a type of energy. Electricity is simply the flow of electric charge. This may sound fairly straight forward, but there is a lot more to this simple statement. One might wonder: Where exactly is this charge coming from? What is obtaining this charge? How is the charge flowing and to where? How does an electric charge power a machine or make lights light up? The answer to all these questions begin with the basic building blocks of…
Jessica Vandeventer 16 March 16 Static Electricity or Electrostatics Purpose/Question- The purpose of this experiment it to explore static electricity and to explore how charges effect one another. Hypothesis– Any like charges will repel each other and any unalike charges will be attracted to each other. Data Tables/ Graphs – Charging Material Pepper Salt Paper Aluminum Styrofoam Uncharged Nothing Nothing Nothing Nothing Nothing Cotton Nothing Nothing Stuck to ruler Stuck to ruler Nothing Fur…
received an electric shock from touching the external surface of the jar even though only the inner surface had been charged. (Wolfram Research Products, 2007) This was a strange and unexpected. Many scientists engaged in debate about the a possible explanation behind the above-mentioned phenomenon. While many of the scientists attributed this phenomenon to a theory termed “action at a distance” which presumes that since insulators block electric current, the only reason why a charge is found on…
Problem: The research questions being examined in this investigation is, How can we generate electricity by using Potatoes to light an electric bulb? Background Information: How does a potato battery work? The copper (Cu) particles pull in electrons more than the zinc (Zn) molecules. On the off chance that you put a portion of copper and a piece of zinc in contact with each other, numerous electrons go from the zinc to the copper. As they focus on the copper, the electrons repulse each other.…
through the increase of its energy. II. Introduction: What is electromagnet? Electromagnet is a magnet that runs on electricity. Electromagnet is created when a copper wire is wrapped around a nail and is connected with batteries, which will gives the electric needed to make the nail into a magnet. There are factors that affect the strength of the electromagnet such as the strength of the magnet depends on the amount of…
Background Information Electricity is a form of energy resulting from the build-up of charged particles, either statically as an accumulation of charge or dynamically as a current (Oxford dictionary, 2015). The effect of electricity can be seen in play daily, whether through a simple light bulb, or a complex application such as providing energy to a power plant. It is often stated that electricity is the most versatile and easily controlled form of energy, and at the point of use it is…
