Strength of the electromagnet

Strength of the electro attractivenessAim To investigate how assorted factors affect the susceptibility of the electromagnet.IntroductionThere are totally two factors that I am going to investigate in this experimentm F1 How the itemise of coils affects the lastingness of the electromagnet.m F2 How a change in genuine affects the persuasiveness of an electromagnet. meditationm F1 I think as the number of coils increase the potential of the electromagnet would too increase.m F2 I think as the sure increases the durability of the electromagnet would also increase.Variablesm F1* self-employed person deed of coils.* Dependent Distance at which compass provoke deflects.(+/-0.05 cm) Constants Current, diameter of the wire, temperature, same iron core.m F2* Independent Current (+/-0.01amps) Dependent Distance at which compass needle deflects.(+/-0.05 cm) Constants emergence of coils, diameter of the wire, temperature, same iron core.Apparatus* Power Supply* Ammeter (0.01amps) * Electromagnets with different number of coils* Plastic Ruler (0.05cm)* Plotting Compass* Crocodile clip wires* Rheostat subroutine Using crocodile clips connect the circuit in the following way F1 fall an iron smash and with the help of a nichrome wire, coil it around the nail 5 times. Switch the circuit on and wait for a minute. eminence down the constant current. Take the gameting compass and steadily place it shoemakers last to the electromagnet and swoop it away in a straight line manger the needle deflects slightly to one side from its vertically straight position. bewilder a ruler from the north pole of the electromagnet and note the quad where this divagation occurs. This where the magnetized expanse lines would approximately end, and hence to a greater extent the distance more the field lines and greater the strength. Repeat the steps above but with 10, 15, 20, 25, 30 and 35 coils. For the same number of coils measure the distance of deflection 2 times for a se cond trial. F2 Using the same circuit instanter adjust the variable resistor so that u have a current of 0.5amps flowing through the circuit. Make the constant number of coils to be 10 coils. Take the plotting compass and steadily place it close to the electromagnet and slide it away in a straight line till the needle deflects slightly to one side from its vertically straight position. Place a ruler from the north pole of the electromagnet and note the distance where this deflection occurs. This where the magnetic field lines would approximately end, and hence more the distance more the field lines and greater the strength. Repeat the steps above but with 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0 and 5.5 amps. For the same current record the distance two times for a second trial. desolate Data TableF1 Effect of the number of coils on the strength of the electromagnet.Number of Coils of electromagnetDistance of deflection from North punt of the magnet(+/-0.01cm) attempt 1Trial 25 1.71.9104.95.1157.67.5209.59.52512.312.13014.8153516.917.2Constant Current0.75 AF2 How changing current affects the distance at which the needle deflects.Current (+/-0.01A)Distance from North Pole of the magnet(+/-0.05cm)Trial 1Trial 20.51.31.21.02.93.01.54.64.62.06.26.32.57.98.03.09.39.53.510.710.84.011.611.84.512.112.35.012.612.95.512.812.8Constant No. of Coils10Processed Data TableThe only processing that stack be done in this experiment is to find the average distance for the investigations for both(prenominal) the trials and hence making it easier to make the graph.F1 Effect of the number of coils on the strength of the electromagnet.

As the number of coils increases the strength of the electromagnet also increases. There is a confident(p) co-relation and this can be proved by theory as well. As the number of coils increase, the magnetic field of each coil also increases and hence a larger magnetic field would cause the electromagnet to be stronger. There is only one anomaly in our results at 20 coils and this can be neglected as it is a very pocketable anomaly.F2 In this graph also we notice that there is a positive co-relationship and hence the current is proportionate to the strength of the magnet. As current in a circuit increases the strength of the magnet would also increase as the coil is provided with more charge and hence the field lines would be spreading over a larger area and the strength would be l arger. unless in this graph afterwards 4.0 amps the graph is no longer proportionate. This can be due to the large amount of heat generated in the wires do more resistance and the value of current would have changed and hence the write out in the graph.ConclusionOur hypothesis for both the factors was proven right by our graphs. Strength of an electromagnet is proportionate to the current and the number of coils in the solenoid. As the number of coils increase the area of the magnetic field lines also increases hence a stronger electromagnet is produced. It is the same for an increase in current. But after a certain current it becomes arduous to maintain other constant factors like temperature which competency cause wide results.Evaluation We could have taken more trials to cash in ones chips better results. We could have used an insulated wire so that the wire habitude heat up so fast and it wouldnt have changed our results. The current wasnt forever and a day exact. It k ept fluctuating hence it may have given inaccurate readings. The exact distance where the needle turned would be very tough to find out as it turns over a range of distance hence that may have given inaccurate results.Fair ladder* The distance between the coils was kept the same in all the trials.* For the low gear experiment we kept the current constant so that we can fair compare the results.* For the second experiment we kept the number of coils the same so that we can fairly compare the results.* And for both the experiments we kept the same visible of the core and the wire.Safe Test As it was dealing with electricity we make sure we did not touch any open ends to prevent ourselves from getting a shock. Also we did not touch the wire right after the experiment was over as it may have been quite hot.
