This calculator estimates the magnetic field strength at a specific distance from a rectangular magnet. It utilizes the fundamental principles of electromagnetism, converting the magnet’s field strength from Gauss to Tesla, calculating the magnetic dipole moment from the magnet’s dimensions and magnetization, and applying these values to derive the field strength at a chosen distance. This tool is particularly useful in applications where understanding the magnetic field’s intensity and distribution is crucial, such as in designing magnetic circuits, sensors, or motors.
