Magnetic Field Calculator
Quick calculation for NdFeB
Free · Designed for iPad. Not verified for macOS.
A quick NdFeb Magnetic calculation tool for your design reference.
Still struggling with complex formulas and tedious calculations for magnetic circuit design? "Magnetic Circuit Calculator" is designed specifically for engineers, creators, and developers of magnetic applications, bringing you "one-stop" magnetic circuit calculations for solenoids and block magnets!
Simply input the key parameters of the magnet (solenoid diameter, length; block magnet length, width, height), and the App will instantly calculate the "central surface magnetic field strength" based on industry-standard formulas. More importantly, it can simulate the magnetic field performance under different measurement gaps, helping you predict the real-world performance of your magnet in practical applications—whether it's the starting force in equipment development or performance verification during product testing, providing you with intuitive reference data.
