Researchers from the Chinese Academy of Sciences set a new record on August 12, 2022, of 45.22 teslas (T, the standard unit of magnetic flux density) using a hybrid magnet.

Magnetic flux rises, ... Its display of the computed magnetic flux density B diffusing into part of the plunger armature of Fig. 1 is shown in Fig. 4 at 20% diffusion time τ m.

While the researchers were hoping that the field would reach 700 teslas, the unit used to measure magnetic flux density or informally, magnetic field strength. Instead, the field reached 1,200 teslas.

Magnetic measurements in household and work environments demonstrate measurements below 0.1mT, or 1G, at distances greater than 16cm, or 6.3in, from various appliances and tools.

Jupiter's magnetic field is profoundly different from that of all other known planets — it essentially has two magnetic south poles instead of just one, a new Nature study finds.
