Does a rising barometer mean cool air or warm air?
It means higher atmospheric pressure, which is generally caused by cool air.
How does lamination affect the magneto-motive force across the air gap of a magnetic circuit?
It doesn't. There are three things that can affect this force: another magnetic field, another conductor within the field, and the size of the gap itself, of course.Lamination is, in essence, insulation, and anything non-magnetic and non-conductive within the field is transparent to the field itself - it's as if it weren't there.
How does the section of iron coil influence the magnetic field?
Do you maybe mean an 'iron core?' If so, an iron core strenghthens the magnetic field significantly. *If the coils are wound closer together the fluxlines are more dense and increase the strength of the field slightly (an iron core strengthens the field by allowing the magnetic field to propagate inside it better than air).
What can make iron move without touching it?
Applying a magnetic field can make iron move without physical contact. Iron is a ferromagnetic material, which means it can be magnetized. When a magnet or magnetic field is brought near iron, it can induce a magnetic force that causes the iron to move. This phenomenon is the basis for many applications, such as electric motors and magnetic levitation.
When it is cloudy is air sinking or rising?
rising
Do birds fly because of a magnetic field?
No. They fly by means of forces they create by manipulating air with their wings and tails.
What feature of an object does not affect air resistance?
Its magnetic field and its color.
What feature characteristic of an object does not affect air resistance?
Its magnetic field and its color.
Why is air gap is necessary in particle magnetic circuits?
Mainly air gap is necessary in magnetic circuit for two necessary reasons: 1. to prevent saturation 2. to allow an object to move in the magnetic field
Usually means rainy weather because moist air is rising?
Decreasing Air Presser
What usually means rainy weather because moist air is rising?
Decreaseing air pressure
What does the moon lack that the earth does have?
There are a lot of things. Some are: Air, water, life, magnetic field.
What is happening to weather if air pressure increases?
Usually rising air pressure means that the weather will improve.
What is hot air rising?
It means air that is hot that is going upwards.... What else could it possibly mean?
What are the conditions that oppose or resist motion?
mass/inertia, static and dynamic friction/ weight, air/wind, magnetism (in the case of a magnetic object in a magnetic field), ...
What is a moving iron galvanometer?
A moving iron galvanometer is used to intensify the magnetic field by reducing the length of air gap across which the magnetic flux has to pass.
What weather do you think is coming when air pressure is rising?
If air pressure is rising (called a "rising barometer") it indicates fair weather coming.
