The scientists applied a force to the ions by imposing an additional electric field on them.
ECONOMIST: Scientists measure a few yoctonewtons for the first time
The ions can then be pulled out of the gas by a strong electric field.
Dr Fenn overcame this by using an electric field to spray them into the chamber.

HSS' transducer is a 28-micron-thick plastic film that flutters when exposed to an electric field (because it is "piezoelectric").
The trace of this electrical charge left behind in the fingerprint is imaged using an electric field microscopy system.

And when a magnetic field line vibrates, he says, it makes an electric field which excites current in wires.

Bacteriorhodopsin has the habit of changing from blue to pale yellow in an electric field, which might be useful in colour displays.
If they survive as the vessels move through the electric field, perhaps they could escape back into the water on the other side.
Helium nuclei are positively charged and thus easier to rein in using an electric field, in order to strip them of their energy.
The atoms in question were stripped of their outer electrons and trapped in an electric field, in a vacuum, at extremely low temperatures.
As for the liquid lens, Nippon Electric Glass' version uses low-power electric field to control its liquid crystal molecular orientation, thus changing the focal point.

Another way of growing snowflakes is to use an electric field.
When an electric field is applied to a microcapsule, the pigment particles within it move, turning one side of the capsule white and the other black.
When they hit the electric field at the end of the cylinder, they bounce off it, spiral back towards the entrance, where they run into matter, and annihilate.
This concentrates the electric field and minimises the required voltage.
Mass spectrometry works by evaporating molecules, giving them an electric charge, and then applying an electric field to them and accelerating them through a vacuum chamber to a detector.
ECONOMIST: This year, the Nobel authorities have shown a deft touch
My proposal with this fellowship will use the novel method of applying an electric field gradient instead of chemical substitution to induce charge carriers in large gap insulators, and thereby create new superconductors.
In the Nature study, Brian Naranjo and colleagues, from the University of California-Los Angeles (UCLA), initiated fusion of heavy hydrogen, or deuterium, using the strong electric field generated in a pyroelectric crystal.
BBC: NEWS | Science/Nature | Table-top fusion 'demonstrated'
There has been some informed speculation, and among what I have read, there seem to be more votes for it being an electric field (EF) sensor than any other explanation.
FORBES: Leap Motion Is Putting Its Future Into The Hands Of Software Developers
Although they have not been found to cause any harm, the cables on conventional pylons, which transmit a three-phase alternating current, generate a strong electric field and a continuous buzz of low-frequency radio waves.
The idea is to make the channel as thin as possible, allowing the electric field generated by the gate to penetrate the entire thing, thus improving the control that the gate is able to exert.
As the particles enter the trap, the magnetic field forces them to travel in spiral orbits so that they cannot crash into the walls of the cylinder, and a strong electric field plugs up the far end, corking up that route of escape.
Malcolm MacIver and colleagues at Northwestern University have created an "artificial electric-field sensing system that could ultimately give robotic subs the same additional sensory capabilities" as found in weakly electric fish.
ENGADGET: Robotic submersibles take on fish-like sensing abilities
He has been electric on the field and personable off it.
FORBES: Victor Cruz Could Hurt Marketability With Contract Talk
Creating a magnetic field using electricity is easy: an electric current flowing in a wire generates a magnetic field around that wire.
ECONOMIST: Recreating the planet's magnetic field in a laboratory
The metal returns up the outer cylinder, and electric currents create a magnetic field.
The method works because the electrical field polarises the electric charge on water molecules in the air around the icy tip and then draws them in electrostatically.
What about the field of utilities and electric energy?
FORBES: The Economist: Innovation Almost Dead. Perhaps Not So In Electricity
Several companies have already started field-testing battery-electric passenger cars and light trucks for use in their fleets.
