An investigation into how the strength of an electromagnet is affected by varying the current Introduction I am investigating whether, and if so, how an electromagnet is affected by varying the current. An electromagnet is a magnet created by winding a wire around a soft iron c-core and running a current through the wire. Current is measured in Amperes (A). Variables available Voltage Current ·N0 of coils around the c-core Size of the c-cores (thickness/length) Type/size of the wire coiled around the c-core I chose to use current as my variable. I decided this because I have access to accurate equipment to measure the current, when I change it. The other available variables will be kept constant throughout the experiments. Aim I aim to find how varying the current in an electrical circuit affects the strength of an electromagnet. Background Scientific Knowledge My c-cores that I will be using will...
