Abstract
In 1820, the correlation between magnetic field and electricity was discovered by physicists and led to the study of electromagnetism. Magnets put charge particles (electrons) in motion, creating magnetic fields that make magnetic forces. This force can be measured through the use of a magnetometer, which requires real magnets and time to put the experiment together. These magnetic fields are not uniform, with their strength varying throughout the magnet from the surface to the core. Another option is running computer simulations to measure the magnetic fields of magnets. In my work, I coded with Python a permalloy magnet in Mumax3 and then ran simulations of varying depths on a permalloy magnet to reveal their magnetic fields. My data supports that the field strength of a permalloy magnet is strongest in the center and is weakest at the surface.
