magnetic fields. This so-called algebraic convention supports arithmetic comparison of north and south polarity values, where the rela-
tive strength of the field is indicated by the absolute value of B, and the sign indicates the polarity of the field (for example, a –100 G
field and a 100 G field have equivalent strength, but opposite polarity).

The value of dI is the difference between 90% of I
For t > t
Maximum current limit is equal to the maximum I
Magnetic flux density, B, is indicated as a negative value for north-polarity magnetic fields, and as a positive value for south-polarity
