What Affects the Strength of an Electromagnet? obtain What is the effect of increasing the current and increasing the turn of coils when picking up account clips?Definition First of all, an electromagnet has to be defined. An electromagnet can also be called a Solenoid, Which consists of a core of iron and then electrify is mantled round it. PredictionI predict that as the current carried in the fit out gets stronger, so will the magnetic bailiwick surrounding the electromagnet. Therefore, I think that the count of paper clips picked up will increase as the potency gets higher until the electromagnet cant pick up any more paper clips. I also predict that the more coils wrapped round the telegram creates a bigger magnetic field allowing more paper clips to be picked up.VariablesThickness CoilsLength of wireCore MaterialIf the paper clips argon already slightly magnetized from previous experimentsWeight of the piececlipsNumber of Paperclips for saleEquipment Mat - (To protect the surface of the bench) Power Pack - (To control the voltage of the current) *Battery Pack (To control the voltage of the current)Crocodile Clips - (To take the electricity to the Electromagnet)Paper Clips (To test the conductivity of the Electromagnet)Electromagnet conjure Nail - (to act as a core) Wire - (wrapped round the core)Test the Voltage Method 1. Take the Iron terminal and wind the wire around it, loss the two ends of the wire free.2. Plug two crocodile clip leads into the Power bunch up and attach for each one crocodile clip to a different end of the wire which is wound around the rod cell.3. Turn on the power to the required voltage (I had a task with the power pack because they kept short circuiting so I distinct to use a battery pack but they would drain very quickly and could only test 2, 4, and 6 volts) and then bring the boxwood of paper clips up so that they are touching the Iron rod4. If there are any paper clips still hanging, take them strike and count them and record the results The above method was repeated at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 & 12 Volts.Testing the Number of Wires Method 1. Take the Iron rod and wind the wire around it 10 times increasing the number of coils by 10 each time up to 100 coils, leaving the two ends of the wire free.2. Plug two crocodile clip leads into the Power pack and attach each crocodile clip to a different end of the wire which ... ...4.605051455149125.005053454648ConclusionThe results did show that my predictions had been right. The amount of paper clips increased by increasing voltage or by increasing the no. of coils(as Shown on the graph). The fact that the electromagnet gets stronger or weaker as you wobble the voltage is a useful one and the fact that the magnetic field gets bigger depending on how many no. of coils and gets stronger for how much voltage is passed by dint of the coils.Probably the reason that some of the results were anomalous because some of the paperclips ma y shake become magnetised, or the Rod may have become a weak permanent magnet. My best fit line didnt pass through the origin, although it came very close. This is probably because the iron rod became slightly magnetised and acted as a weak permanent magnet, before it was connected.
