The magnetic field is not only stronger than anticipated-3. 7 to 5.5 microgauss-it's also tilted off the galactic plane of the Milky Way by about 30 degrees,

"Voyager data show that the Fluff is much more strongly magnetized than anyone had previously suspected - between 4 and 5 microgauss," said Merav Opher, a NASA Heliophysics Guest Investigator from George Mason University.

Astrophysical magnetic fields are often measured in units of gauss; the Earth has a magnetic field of approximately 0.5 gauss (or 500,000 microgauss).

Therefore, 4 to 5 microgauss may seem pretty weak in comparison, but this field covers astonishing scales, appearing to wrap around a very tenuous hydrogen/helium gas, possibly helping the Local Fluff maintain its structure.
