It is a phenomenon associated with stationary or moving electric charges. Electric charge is a fundamental property of matter and is borne by elementary particles. In electricity the particle involved is the electron, which carries a charge, as negative. Electricity is not a form of energy. No credit card required, no obligation to purchase.

For example, if two objects are rubbed together, especially if the objects are insulators and the surrounding air is dry, the objects acquire equal and opposite charges and an attractive force develops between them. The object that loses electrons becomes positively charged, science homework help 7th grade, and the other becomes negatively charged.
When one object is rubbed against another, static electricity is created. This is because the rubbing creates a negative charge that is carried by electrons.
These electrons build up to produce static electricity. eTutorWorld offers affordable one-on-one live tutoring over the web for GradesTest Prep help for Standardized tests like SCAT, science homework help 7th grade, CogAT, SSAT, SAT, ACT, ISEE and AP.

In most objects, all the atoms are in balance with half of the electrons rotating in one direction and half rotating in the other direction.
Magnets are quite different with the atoms at one end having electrons spinning in one direction while those at the other end spin in the opposite direction. The force of the magnetic field flows from the North Pole to the South Pole. If you hold two magnets close to each other you would find that if you try to push the two North poles N or the two South poles S together, they repel each other.
If you put the North Pole N near the South Pole Sthey attract each other. Each electron is surrounded by a force called an electric field. When an electron moves, it creates a second field — a magnetic field.
When electrons are made to flow in a current through a conductor, such as a piece of metal or a coil of wire, the conductor becomes a temporary magnet — an electromagnet. Electric current flowing through the wire produces magnetic field.
The direction of magnetic field depends on the direction of electric current. A changing magnetic field produces an electric current in a wire, science homework help 7th grade. The relationship between electricity and science homework help 7th grade is called electromagnetism.
A magnetic field pulls and pushes electrons in some objects near them to make them move. For example, in copper metal electrons those are freely movable, science homework help 7th grade. When a magnet is swiped along quickly through a copper wire, electrons move and so electricity is made. When current flows through any wire it creates a magnetic field around the wire as it goes along.
Electrostaticsthe study of electric charges at rest, was initially found by the ancient Romans who observed how a comb after brushing would attract particles. It is known that electric charges are in two different forms, positive charges and negative charges. Like science homework help 7th grade repel each other, and differing charges attract. The force that attract positive charges to negative charges weakens with distance, but is very strong — up to 40 times stronger than the pull of gravity at the surface of the earth.
This fact can easily be described by a small magnet that can hold or suspend an object. The small magnet exerts a force at least equal to the gravitational from the entire Earth. View Our Reviews On TrustSpot View Our Reviews On TrustSpot.
