What happens to the temperature of a liquid as it changes from a liquid to a vapor?
The liquid vaporizes and the temperature increases as the volume also increases.
How can electric currents and magnets exert force on each other?
Electric currents and magnetic fields are by nature and by definition related to each other. In general, a magnetic field is created by the rotation of charge. If you imagine an electron following a circular path, a magnetic field would be created in the direction perpendicular to the plane of the circle.On the other hand, electric current is defined as the flow of charge. So, an electron flowing along a wire results in current flow. This also means that the electron following a circular path (as above) creates an electric current along that same path.If a circular flow of current results in a magnetic field perpendicular to the circle, what happens for current flow along a straight wire? Basically, we see a magnetic field which bends around the wire. Imagine exactly the reverse as before, with the magnetic field circling around the direction of current flow.This basic relationship between electric current and magnetic fields results in some interesting interactions:1. Many electromagnets work by the following principle: A coil of wire is made so that when voltage is applied the current will follow a circular path. As discussed above this circular movement of charge results in a magnetic field. In this case, you can imagine the direction of the magnetic field as the line through the center of the wire coil.2. The Hall Effect: When current is applied across a conductive slab and a magnetic field is applied perpendicular to current flow, a voltage is generated in the third perpendicular direction. This occurs due to the interaction of the magnetic field generated by the flow of current and the applied magnetic field.
What happens when you stroke a needle 20 times with a magnet?
it becomes magnetic :)
Air temperature changes as altitude increases because of?
it is awesome this answer is gravities pull on oxygen
What are the changes in width of attached gingiva with age?
Width of attached gingiva increases with age.
Why call light as E M wave which is not having neither electric nor magnet?
Electromagnetic waves, like light, do involve changes in the electric and the magnetic field. These changes propagate at the speed of light - as a wave.Electromagnetic waves, like light, do involve changes in the electric and the magnetic field.

What is induced by an electric field that changes with time?
A magnetic field
Give one example when magnetic energy changes into electric energy?
A discharging inductance.
When a force on an object increases how does the object acceleration change?
Changing the magnitude or direction of forces exerted on an object changes the net force (sum of all forces) exerted on the object. The net force exerted on an object is defined as mass times acceleration (F = ma), where mass, m, is constant. This means that when the net force exerted on the object changes in magnitude (or direction), its acceleration will also change in magnitude (or direction). In addition, acceleration is defined as the change in velocity, so when the magnitude (or direction) of acceleration changes, the magnitude (or direction) of velocity will also change.
Are electromagnetic waves characterized by rarefactions and compressions?
No they are caused by changes in magnetic and electrical fields. When a magnetic field changes it causes an electric field that is perpendicular to it. And vice versa a changing electric field causes a perpendicular magnetic field. These changing fields propagate outwards at the speed of light and are what is meant by an electromagnetic wave.
What most occur to produce electric current?
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
In an electromagnet as the electric current changes what happens to the magnetic field?
the magnetic field would constantly change, that's why the AC current is converted to DC current
When you turn on a electric fan electrical energy changes into which kind of energy?
First changes into magnetic energy that leads to mechanical energy along with some heat energy
Can a electric current affect a compass?
Yes. An electric current is surrounded by a magnetic field, and this will affect a compass. Please note that this is more noticeable in the case of DC - for AC, the current changes all the time, it changes very quickly, and the AVERAGE value of the magnetic field is zero.
What do you mean when you say that light is a electromagnetic?
Electromagnetic wave, actually. That means that changes in both electric and magnetic fields propagate as a wave.
What happens to earthquake magnitude as the length of the moving fault changes?
As the length of the slipped fault increases (all other factors being equal), so too does the magnitude of the earthquake.
What happens when a lamp plugged into an electric outlet is turned on?
the form of energy changes and the total of energy increases
