Or, in the case of beams of atoms, by manipulating electric fields to achieve the same effect.
The Food and Drug Administration just approved a hat that generates electric fields to fight a deadly form of brain cancer.
FORBES: Cancer-Fighting Electric Hat Proves We Live In The Future
Materials like this crystal produce these electric fields when they are heated.
BBC: NEWS | Science/Nature | Table-top fusion 'demonstrated'
The researchers first showed that structures on the animal's head were probably sensory organs, then found it could detect electric fields in water.
Such fields are everywhere, and the researchers suggest that their approach could be used for mapping electric fields on the surfaces of materials and getting a better understanding of their properties.
ECONOMIST: Scientists measure a few yoctonewtons for the first time
That conundrum was solved by getting the high-frequency signals to penetrate deeper using alternating waves of electric and magnetic fields.
ENGADGET: Stanford researchers make heart implant powered by radio waves, put batteries out of a job
They may not be able to drive immediately, and should stay away from devices that create strong electric or magnetic fields.
One of the benefits of this technique is that it allows for a relatively rapid detection of tiny electric and magnetic fields.
ECONOMIST: Scientists measure a few yoctonewtons for the first time
While trapping of charged normal atoms can be done with electric or magnetic fields, trapping antihydrogen atoms in this "hands-off" way requires a very particular type of field.
In 1997 the National Research Council issued a major report on the health effects of exposure to power frequency electromagnetic fields (EMF), such as those due to electric power lines.
Helium nuclei have an electric charge, so they stay in the tight hug of the magnetic fields.
