Different end geometries are used to test the optimal conditions for low adhesion and increased dynamic response to an actuating external rotating magnetic field. When subjected to a magnetic field as ...

Smaller, streamlined electronics make lubricant-free, low-friction magnetic bearings feasible for more rotating machines. • Magnetic bearings support rotating shafts in five axes without solid ...

Therefore, a magnetic field diode in which the field can only be transferred coil-to-coil in one direction should not be possible. One-way system: illustration of the diode coils set within the ...

First, propulsion via a rotating magnetic field is ten times more powerful than propulsion via a static magnetic field. The latter merely sets the direction and the bacteria have to move under ...

In response to a rotating magnetic field, the dipole moves like a compass needle, aligning all the beads along the same ...

First, propulsion via a rotating magnetic field is ten times more powerful than propulsion via a static magnetic field. The latter merely sets the direction and the bacteria have to move under ...

At the vascular wall, the rotating magnetic field propels the bacteria forward in a circular motion. To better understand the mechanism to cross the vessel wall works, a detailed look is necessary: ...

Schürle therefore wants to make E. coli bacteria magnetic as well. This could one day make it possible to use a magnetic field to control clinically used therapeutic bacteria that have no natural ...

These bacteria of the genus Magnetospirillum respond to magnetic fields and can be controlled by magnets from outside the body; for more on this, see an earlier article in ETH News [https://ethz ...
