Respective, opposed ferromagnetic armatures (17, 18) are connected to the diaphragms (10, 11).

This “something” has abnormally high content of iron and other ferromagnetic materials.

The ferromagnetic circuits of the two actuators assigned to two valves of the same type of a common cylinder are contained in a common housing.

These steels are magnetic but can’t be hardened or strengthened by heat treatment.

As shown in the figure below, the rotor is composed of a stacking of ferromagnetic discs.

These steels are magnetic but cannot be hardened or strengthened by heat treatment.

As shown in the figure below, the rotor is composed of a stacking of ferromagnetic discs.

These steels are Ferro-magnetic but cannot be hardened or strengthened by heat treatment.

The bases also have embedded magnets allowing to make them stick on ferromagnetic materials.

The magnetoresistive element has a laminate film structure formed by laminating a pair of ferromagnetic thin films through a non-magnetic metal layer.

The magnet (10) is releasably latched in both its write and erase positions by ferro-magnetic elements (162) mounted to the guide (144).

A large output signal from the secondary side is achieved by a large magnetic coupling of the primary conductor and secondary coil without the use of ferromagnetic materials.

Respective, opposed ferromagnetic armatures (17, 18) are connected to the diaphragms (10, 11).

In the gap (N-S) between the poles are placed elements of ferromagnetic material forming local magnetic fields inside the column of the ferromagnetic liquid (3).

The magnetic labels (50) may be magnetic nanoparticles or magnetic microbeads.
