B·Hmax
The greatest possible product from B and H within the demagnetisation curve. The greater the BHmax value of a material is, the smaller may be the magnetic volume required for a given application task, under identical conditions.

BH tracer
See hysteresisgraph.

Bitter coil
Axial coil in which current flows through disks in an helicoidal path, instead of flowing in a set of windings. The advantages are better cooling and robustness.

Bonded magnet
Materials composed by ferrite or rare-earth powders embedded in rubber, resins or plastics. They may be formed by rolling, extrusion, compression and injection molding, and they can be flexible or rigid. They have lower levels of B compared with the original magnetic material, but they can be formed in complex shapes.
