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 ...

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 ...

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 ...

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 ...

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 ...

That is, until you coat such particles with a ferromagnetic material like iron, make them spin using an external magnetic field and watch them make their way against gravity.

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 ...
