Hi guys, I have chosen the variation of magnetic field strength under different temperatures for my high school physics experimental investigation. We had a guassmeter at school, however it has had a few problems, and so ive dicided to use a compass. My question is, how do i use the angle of my compass that is created by my magnet, to determine the magnetic field strength of my magnet?. I will keep the distance between the magnet and compass constant in each of my measurements. Please recommend the formulas i need to use . Thanks I have seen an article regarding magnetic field strength with distance, where formulas such as these were used: m× (HE +HM) = 0 mHE sin θ = mHM cos θ tan θ =HM/ HE Can such formulas, be applied to my situation?
