When a magnet is moved alongside a wire what happenes?
the electrons in the wire begin to flow
Is it possible to create an induced charge separation on an insulator?
No. To get induced charge separation you must have electrons in outer bands that can easily be moved by an electric field. Conductors have these electrons available but insulators do not.
When is a substance is negatively charged?
When it's ions have more elecrons than protons
Is cotton a good sound insulator?
Cotton is not particularly good as a thermal insulation. It achieves its results by trapping air within its bulk, and air is close to the best insulator. Wet cotton is an EXTREMELY poor insulator, and in the outdoors world it is known as 'the death cloth' because of its performance on those suffering hypothermia. Even slightly damp cotton loses a lot of its thermal performance because it wicks the water easily.
What is the Cause of the movement of electrons?
Force is the cause of movement. Electrons can be moved by gravitational force F= GmM/r^2 and electric force produced by the Electromagnetic fields, F=eE and F= evB= e(-v.B + vxB).
Which famous scientist discovered how water can be moved by objects?
Archimedes
Who discovered electrons moved around the nucleus?
Ernest Rutherford
What is the name of the famous scientist who discovered that water can be moved by objects when he sat in the bath?
Archimedes of Syracuse.
Why are metals good for electrical conductors?
Metal atoms have a few lightly-bound electrons in their outer shells, and these electrons can be easily moved by a modest electrical potential. This makes them good conductors.
Who discovered the elctromagnetism?
Electromagnetism was discovered by Hans Christian Orsted, a danish scientist in 1820. Whilst preparing for a lecture, he noticed that a compass needle could be moved by the electric current in a battery. Hope that helps!! x
What is the contribution of a foriegn scientist?
Ernest Rutherford was the first person to transmute an element. He also produced the model of an atom in which a tiny nucleus was surrounded by a vast space in which the electrons moved.
How was Eli Whitney's motivated to become a scientist?
what moved him to become a scientist was that when he was little he would always be in the garage tinkering with his dads tools. what moved him to become a scientist was that when he was little he would always be in the garage tinkering with his dads tools.
Which scientist organized animals into groups according to how they moved?
Aristotle
Who proposed that this is where electrons moved around the nucleus?
John Dalton
What famous German scientist moved to the US on this day in 1933?
Albert Einstine
Energy associated with electrons that have moved from one place to another?
Electricity
Which part of an atom can be moved to charge a material?
The electrons on the outer shell
