Physics Coursework Rebecca Newiss 10O2 Introduction In this investigation I aim to find out what effect increasing the number of turns in a coil on an electromagnet will have on the strength of the electromagnet, and the weight it is capable of holding. I predict that the higher the number of turns there is on the core the higher the amount of weight the magnet will hold. Also I predict that, if I double the amount of turns in the coil on the core, the magnetic field strength of the electromagnet will also double, I will find out if this is true from the weight it is capable of holding. E.g.) 20 turns will hold 50 grams 40 turns I predict will therefore hold 100 grams Above is a predicted example of what I think might happen when I increase the numbers of turns in a coil on an electromagnet. I do not know that...
