Therefore, if the distance is doubled, the strength drops by a factor of 4. In each experiment I shall keep the other variables the same. You will use these wire tails to connect the coil to the battery. The wire used- High resistance wire will cause less current to flow and hence a weak field will be obtained. For any other use, please contact Science Buddies. A large core has more copper wire wound around it.

Investigating the Strength of Electromagnets :: Papers

electromagnet strength factors

Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core. My aim is to find out the factors that affect the strength of an electromagnet. This will make it more difficult to keep the turns tightly packed against each other, as they will tend to fall into the threads of the bolt. Prediction I predict that as the current carried in the wire gets stronger, so will the magnetic field surrounding the electromagnet. The Electromagnet uses this principal by having several individual loops magnetically joined together to produce a single coil.

Try comparing the number of paper clips that electromagnets with different core materials can lift. When ferromagnetic materials are used in the core the use of relative permeability to define the field strength gives a better idea of the strength of the magnetic field for the different types of materials used. More current through the wire in the coil. The Factors That Affect the Strength of an Electromagnet Planning What I am trying to find out? It has a north pole on one side of the loop and a south pole on the other. This simple classroom experiment allows us to pick-up a large quantity of clips or pins and we can make the electromagnet stronger by adding more turns to the coil. Wrapping the copper wire around an iron nail, increasing the current.

Four Factors Affecting Electromagnets

electromagnet strength factors

The more turns on the coil, the more the domains are being lined up. Variables: Independent The independent variable which we can control is the amount of voltage we put through the electromagnet. An air core magnet will have less field … strength than an iron core. You can leave the paper form in place. We also know that the electricity from the power pack and the movement within the wires creates magnetism. Current I through a wire produces a magnetic field B. If you do this after each turn, your wire turns should line up nicely.

Make a holder for a bar magnet. Otherwise, we also will consider that if both the mind and body exist, and then there could be a number of types of relationships. The addition of a soft iron core nail will renforce the generated magnetic field as the nail will become magnetised. If not, try re-sanding the ends of the magnet wire until all of the reddish insulation is gone, then reconnect and retest the electromagnet. Calculate the equivalent relative permeability value. For making comparisons, it would be ideal to have core materials that are the same diameter.

When electric current flows through a wire, it creates a magnetic field. Diagram 2, showing the position of the apparatus for experiment two Safety measures Safety is needed during any type of experiment carried out. More factors to … consider: The diameter of the coils, and the inductor core material. I will connect the wire to the power pack and set the voltage to 8. Relative Permeability Materials that have a permeability slightly less than that of free space a vacuum and have a weak, negative susceptibility to magnetic fields are said to be Diamagnetic in nature such as: water, copper, silver and gold. Overall, how would you rate the quality of this project? Set equipment up as shown on diagram 3.

Varying any of the four basic elements of an electromagnet allows you to set the field strength as needed. Always disconnect one alligator clip when your electromagnets are not in use. However, some locations are very remote, away from a population who would use the resource, or in a harsh environment where it is difficult to extract the gas. Sliding the core partially out of the coil will weaken the field, because less of the metal is within it. By increasing the size of the core you also increase the strength of the electromagnet. Perhaps they were inquiring about a physical skill such as how much weight you can bench press.

First off, the two main factors are the power source and the number of windings in your Electromagnet. With each variable we will test it three times to get fair results, and we shall record the number of paper clips picked up each time. The core is called the solenoid and has cooper turnings wound around it. The product of Hydrogen Peroxide is oxygen in a gas state thus it is mandatory to use the gas pressure sensor. The different factors that affect the strength of electromagnets are the temperature, amount of current passed through the wire, the length of the core, the thickness of the wire used for the coils and the number of turns of the electromagnet. Number of Turns Number of Paper Clips Picked Up 1 2 3 4 5 Average 50 100 150 200 Table 1. Overall, how would you rate the quality of this project? Electric and magnetic electromagnetic forces can be attractive or repulsive, and their sizes depend on the magnitudes of the charges, currents, or magnetic strengths involved and on the distances between the interacting objects.

This matches my prediction, this is because every turn in the coil, acts as if you were stroking a piece of unmagnetized iron with a magnet. You can strip the insulation off the remaining part of the wire tail. Apparatus: · Iron Rod · Leads · Power Pack · Crocodile Clips · Insulated Wire · Iron Nails · Voltmeter · Plastic Beakers · Electronic Balance Hypothesis: I expect the strongest electromagnet to have a 'soft' iron core; the highest number of coils 45 ; the strongest voltage 10V and current and have the coils evenly spread across the iron rod. An electromagnet can also be called a Solenoid, Which consists of a core of iron and then wire is wrapped round it. According to Thomas Patterson, several factors affect the presidential leadership in the United States of America and other countries Patterson: 413. It causes materials like iron, steel and nickel to attract to it. Please note that you will need a free Ask an Expert account in order to post questions.
