Is air diamagnetic?

Yes, air is considered to be diamagnetic. This means that it has a weak repulsion to magnetic fields, which is a characteristic of materials that do not have unpaired electrons. While the effect is very subtle and generally negligible in practical terms, it indicates that air does not retain any magnetic properties when an external magnetic field is removed.


What is Air Gap of a magnet?

The air gap of a magnet refers to the space between the magnet poles where the magnetic field is generated. It represents the distance over which the magnetic field lines travel and influence external objects. The air gap plays a critical role in determining the strength and reach of the magnetic field produced by the magnet.


What can you infer about magnetic fields and paper?

You can infer nothing about a magnetic field from paper alone, or about paper from a magnetic field. If you put iron filings on a horizontal sheet of paper and put a magnet below the paper, you may be able to visualize the magnetic field of the magnet and thus infer its dipole arrangement.


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).

Do birds fly because of a magnetic field?

No, birds do not fly because of a magnetic field. Birds fly by using their wings to generate lift and thrust. They navigate using a variety of cues, including landmarks, the position of the sun and stars, and Earth's magnetic field.


Can things hover in a magnetic field?

Yes, certain objects can be suspended or "hover" in a magnetic field due to magnetic levitation. This occurs when a magnetic force counters the gravitational force acting on the object, allowing it to remain suspended in mid-air.

What feature of an object does not affect air resistance?

Its magnetic field and its color.


Does iron emit a magnetic field under water?

Yes, iron does emit a magnetic field both underwater and in air. However, the strength of the magnetic field may be affected by factors such as the composition of the water and the presence of other materials nearby.


How can magnets work in space?

Magnets work in space because they create a magnetic field that can attract or repel other magnetic objects. This is possible because the magnetic field is not affected by the lack of air or gravity in space.


Why do magnetic lines of forces prefer to pass through iron than air?

Magnetic lines of force prefer to pass through iron rather than air because iron is a ferromagnetic material, which means it can easily be magnetized and has a high permeability compared to air. This results in a stronger magnetic field within the iron, making it easier for the magnetic lines of force to pass through.


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


Can Magnet attract a steel paper clip through air and water but not glass?

That statement is not true. Yes a magnet will attract a steel paper clip through air or water. No, a magnetic field will penetrate glass as well... probably. Certain types of glass (which are themselves ferromagnetic) might serve to block a magnetic field.


What weather do you think is coming when air pressure is rising?

When air pressure is rising, generally clear and dry weather is expected. Rising pressure indicates a stable atmosphere with sinking air, which typically means calm conditions with minimal chances of precipitation.
