performed — all operations will be performed and displayed in
terms of amperes. Values from 0.001 to 999.99999 are acceptable
for coil constant. The default value is 1.00000 kG/A (or 0.10000 T/A)
unless preset by AMI to match a specific superconducting magnet.
If the coil constant is not explicitly stated within a superconducting
magnet’s specifications, the value can be obtained by dividing the
rated field by the rated current. Note that 1 T = 10 kG.
3.10.2.3 Magnet Current Rating
Caution
The Magnet Current Rating is normally set to match a specific
superconducting magnet. The setting should not be changed unless
a different magnet is to be used; always refer to the magnet
specification before changing the Magnet Current Rating.
A magnet operates within the capabilities of the associated power
supply. Since the supply must be selected from the available
standard ratings, the current limit of the supply, which is not user-
adjustable, is almost always higher than the Magnet Current
Rating.
The Magnet Current Rating is normally preset by AMI to match a
specified superconducting magnet. If AMI is not supplying the
