International Magnetic Solutions has created this on-line calculator to analyse a range of common magnetic applications and generate graphs ofÂ magnetic flux densityÂ (induction) / attractive force / current etc.

In this section we have set up a program offering many useful magnetic analyses, as follows:

• Flux density at a distance from a single rectangular magnet
• Flux density at a distance from a single rod magnet
• Flux density at a distance from a single steel-backed rectangular magnet
• Flux density at a distance from a single steel-backed rod magnet
• Flux density between 2 rectangular magnets facing each other
• Flux density between 2 rod magnets facing each other
• Flux density between 2 rectangular magnets facing each other with steel path
• Flux density between 2 rod magnets facing each other with steel path
• Force at a distance from a single rectangular magnet
• Force at a distance from a single rod magnet
• Force at a distance from a single steel-backed rectangular magnet
• Force at a distance from a single steel-backed rod magnet
• Electrical – magnetic analysis of 3-legged circuit
• Flux density vs magnetizing force for mild steel
• Breakaway force for a rectangular magnet on steel
• Flux density at a distance from a single current-carrying conductor
