hey im a sophomore in high school and I need help with a project o affecting the strength of a magnetic field...... first of all m project is seeing how certain materials can affect the strength of magnetic field, created by a bar magnet and a neodymium magnet. Th field will be measured using a CBL extension sensor from a TI-83 Plu graphing calculator. the independent variable will be placed betwee the magnet and the sensor anywhere from 2-10 centimeters between eac (placed in the middle). The problem is that I tested aluminum and it had no effect on the strength of a magnetic field. While this i obvious, my fear is that other metals fill not affect the strengt and I will receive a failing grade. I need to know what metals ma affect the magnetic field, or anything that will affect it, for tha matter. Other metals will have an effect, but they may not b available to me (or I may not know it)
If you haven't already observed so, I have little knowledge of magnetic field and what may affect it. Any knowledge or insight yo may possess that may be helpful would be greatly appreciated. Than you for your time
