IB Physics Internal Assessment Exemplar: I will investigate the relationship between the enclosed current in a solenoid (27.1mA, 40.2mA, 53.7mA, 80.4mA, 106.7mA), and the magnetic field strength produced by that solenoid (mT). The solenoid will be consistent each trial, consisting of an insulated copper wire wrapped 60 times around an iron core that has a radius of 1cm and length of 15cm. | RevisionDojo
