E.g. the MNP17 magnet has a field, of , so for a particle with elementary charge, , and a momenta, of ,

The aperture of the MNP17 magnet is long, so a particle will exit the field well before entering an orbit. The angle of deflection will be given by,

For a particle, the deflection angle is around . To find the linear displacement of the particle from the point it exits the magnet, over a distance of, say, ,

There is also a displacement in the magnetic field of,

giving a total displacement of . Repeating this at gives

## Approximation

Since , and ignoring the displacement in the field; we can approximate the deflection by

at , or at ;
