electromagnetism - Magnetic flux linkage of a solenoid is equal to BAN, but what is A representing? - Physics Stack Exchange
Are there any equations in identifying the magnetic flux density of a ferromagnetic magnet at a certain distance (for example, a neodymium magnet has a magnetic flux density of 5.31 miliTesla at
