So we have several equivalent tests for a conservative E field ( W = 0) : • It has no

curl: V X E = 0. • It is the gradient of a scalar: E = —VV( because the curl of a

gradient is

When the current returns to

**zero**, then H is**zero**, but the magnetic field B is not yet**zero**because of residual magnetization. (The Greek root of "hysteresis" implies alag.) It is necessary to run current in the primary in the opposite direction in ...
