Magnets in conservation and display of art - permanent magnets are widely used in conservation, restoration, and for displaying works of art.1)2)
This page lists various resources helpful for estimation of mechanical forces which can be generated on art materials due to the presence of magnets.

Magnetic calculators
This section contains a collection of interactive calculators which can be used for computing the values of magnetic fields and mechanical forces acting on works of art by permanent magnets positioned on them, or in direct vicinity of them.
Calculators of force
| Interactive calculators of force click on the link below ↓ | Illustration |
|---|---|
| Magnetic force on a thin layer due to cuboid magnet (useful for magnets of any size, also approximately applicable to cylindrical magnets of the same volume and aspect ratio) |  |
| Magnetic force on a thin layer due to cuboid magnet (simple equation, but based only on the magnetic field on the axis, reasonable accuracy for “long” magnets, such that L ≥ a,b ) |  |
| Magnetic force on a thin layer due to cylindrical magnet (simple equation, but based only on the magnetic field on the axis, reasonable accuracy for “long” magnets, such that L ≥ D) |  |
| Magnetic force between cylindrical magnet and thick steel plate, with air gap (simple equation, but based only on the magnetic field on the axis, reasonable accuracy for “long” magnets, such that L ≥ D, and for small gap g ≪ L) |  |
| Magnetic force between magnet in a cup and thick steel plate (simple equation, but based only on the magnetic field on the axis, reasonable accuracy for “short” magnets, such that L < D, and for small gaps) |  |
Calculators of magnetic field

|---|---|
| Magnetic field H of a cuboid magnet at any point in space (valid at any point outside or inside of the magnet, not just along its axis) |  |
| Magnetic field H of a cuboid magnet (only along magnet's axis) |  |
| Magnetic field H of a cylindrical magnet (only along magnet's axis) |  |
