|
Pressure on the push button «unclosed padlock» position, unlocks the curtain by activating the electromagnet on theopposite side. |
|
The reason why it is called a permanent magnet motor is that the compass needle in the centre is a permanent magnet, not an electromagnet. |
|
The other arm carries a wire coil attached to an electric circuit in other words, an electromagnet. |
|
This lever gives an impulse to the pendulum and is then restored to its original position by an electromagnet. |
|
The explanation is, that the magnetic field coming from the upper electromagnet flows through the lower iron core. |
|
This is made possible by simple reversal of the magnetic field of the electromagnet placed beneath the target. |
|
To do this, it activates an electromagnet which in turn releases the springs. |
|
The transport trolleys feature user-friendly docking supported by an electromagnet. |
|
The power that runs the electromagnet in the contactor, runs through both the start buttons and the safety switch on the cutter-head hatch. |
|
The distance from the rounded tip of the red imprint to the remains of electromagnet measured 32 mm. |
|
This kind of alloy is more powerful than any other kind of electromagnet devices, for the same weight. |
|
|
A support post with an electromagnet provides an extra locking mechanism for the barrier arm in horizontal position. |
|
This tension is used to carry objects that have already been lifted thus keeping the electromagnet cooler. |
|
If you are having trouble finding a magnet around the house, two possible sources include a can opener and an electromagnet that you make yourself. |
|
What difference does voltage make in the strength of an electromagnet? |
|
Plus, he says, their carbon cores could make them stronger than steel, so an electromagnet made from the wires wouldn't need a heavy structure to support it. |
|
It is this small magnetic field that is the basis of an electromagnet. |
|
They consist of an electromagnet that is inserted in the street. |
|
Since lifting magnets are electromagnets, a power source is needed to generate the electromagnet field. |
|
The range includes the unique MagnaSystem using an electromagnet to attach the hose to the vehicle permitting quick getaways and superior capacity for exhaust removal. |
|
Although most of the electromagnet that activated the failure warning flag was not recovered, a piece of the electromagnet remained attached to the upper left corner of the frame. |
|
He used the same apparatus as in his previous experiment, but placed the discharge tube between the poles of a large electromagnet. |
|
Each segment has an electromagnet attached to it, and these are activated by a current that flows from head to tail in more or less the way that a nerve signal flows in a real animal. |
|
The magnet holder, which moves back and forth between the electromagnet at the same frequency as that of the power supply, sets a diaphragm going on both sides, which then changes the valve box volume. |
|
They can test the electromagnet by seeing how much a compass needle deflects, or by counting the number of staples or paper clips the electromagnet attracts. |
|
Other internal doors are closed by an electromagnet, which enables staff to leave without problems, even after the hospital is closed, but cannot be opened from outside the department. |
|
The endoscope, nicknamed ''Mermaid,'' is capable of taking two shots per second, while its driving gear is powered by an electromagnet. |
|
The built-in stop consists of an electromagnet which when activated opens the reed contact in the vehicle and in doing so interrupts the motor voltage. |
|
When current is applied to the electromagnet, this moves the internal control slider in the valve and thus switches the oil pressure between the working chambers. |
|
Along with my tester's Sport Blue Metallic paint, its factory customization had a way of pulling at the eyes like an electromagnet pulling at steel. |
|
The patented Eriez Magnetic Drive Circuit incorporates a lifetime permanent magnet whose poles are intermeshed with those of an electromagnet powered directly by an AC line. |
|
|
Of 3,441 drivers checked, 643 had exceeded their hours while 90 had attempted to conceal this by using electromagnet to disengage their tachograph. |
|
The 50-foot-wide, 15-ton electromagnet attracted a sensation wherever it went during its slow, delicate 3,200-mile journey from New York to suburban Chicago. |
|
The resulting electromagnet, more than 1,800 times stronger than a typical fridge magnet, will be used to test the properties of new materials including superconductors. |
|
Tenders are invited for Low Loss Electromagnet Copper Ballast For Mh Lamp 150 Watts Suitable To Use In 230V 50Hz Ac Supply. |
