What is a Compound Wound Traction Motor?
It is a Direct Current Motor which is wound and creates a magnetic field when energized and does not use a permanent magnet. Jeff S.
If a wire with no current passes a magnetic field of flux will voltage be induced into the wire?
Yes, for as long as the magnetic field is moving along the conductor. A static magnetic field will not induce current, a dynamic field is required.
What is the purpose of the diode inside the relay?
If it is a light emitting diode it is there to let you know that the relay is energized. In my experience, when a DC current is removed from a coil, the polarity of the magnetic field reverses and if it weren't for the diode, the relay would "chatter". The diode polarity is oppsite of the actuating voltage.
What is Electric field stress?
An Electric field stress depends on the mechanical strength of the materials and the stresses that are generated during their operation. During high voltage applications, the dielectric strength of insulating materials are developed when subjected to high voltages.
Automatic induction braking system for vehicle?
I don't see why not. It would have to be electromagets providing the magnetic field, and they would draw electricity from a generator that is powered by the motor. For electric cars, however, the brakes would draw too much power and drain the battery.
Is the temperature field map a static or dynamic field?
dynamic
What is meaning of dynamic elements in electronics?
Dynamic element term is arises on the domain of digital to analog conversion in the field of electronics. if you are looking for dynamic microphone it means this converter applied sound vivration to electrical signal. Dynamic term also arise in the field of diode static and dynamic resistance.
Examples of scientific field quantities?
dynamic and static
What is dc injection braking for ac motors and how does it work?
works with the concept of DC injection braking, where a dc volt is injected into a three phase rotating magnetic field which causes a stagnet magentic field thus bringing the motor to a complete halt.
Do anti-lock brakes reduce braking?
Most experts in the field agree on this. ABS does reduce braking distance on dry or wet pavement if they are used properly. On gravel and snow ABS may increase braking distance slightly. But ABS's main safety feature is not to decrease stopping distance, but is to allow control of the vehicle during an emergency stop, because it prevents wheel lock-up and a skid.

What are some types of scientific field quantities besides static and dynamic?
Nothing
What field areas use dynamic range?
The field areas in wide dynamic range are from shadows to highlights. The term is use to describe the contents of an image file containing such data and the capability of a sensor or other imaging system.
How does an inducted magnetic field influence the direction of a compass needle?
The conducting wire wrapped around the compass is energized creating a magnetic field that counteracts the effects of the Earth's magnetic field and changes the direction of the compass needle.
What has the author Jim Bush written?
Jim Bush has written: 'Dynamic track and field' -- subject(s): Coaching, Track and field
What are 2 aero dynamic implements thrown in track and field?
The shot put and discus.
