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

Try our Online Magnet Design Software, its FREE!

Providing speedy solutions for designers, engineers and inventors, our unique online magnet design tool and calculator generates values of magnetic flux strength at various distances and applications.

Test different concepts quickly and easily.

Provides a range of results to show the effects of varying the Br, thickness, diameter, width or length.

See the outcomes of various design changes and specifications.

Guaranteed to save you lots of time.

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
• Smallest magnet to deliver a specified flux density
• Breakaway force for a rectangular magnet on steel
• Flux density at a distance from a single current-carrying conductor
