actually E usually represents Electric field.  As in E =(kq)/r^2         the units are usually Newtons over Coulombs

Well that book must have a misprint or something because q=CV is not accurate. Actually if the potential of a outside conductor depends on the size, then this is a variable dependent, (and therefore mutable) in structure, shape, and amount of conduction based on the charge of q. For if C=q/v, then the isolated conductor's potential to change will be hinder and therefore not fully capable of allowing a full transformation for V due to the charge (power) of q.

You might start by contacting the power company.  If you have concerns about eletromagnetic interference, they should be willing to help you.

Magnetic flux and electric flux are always linked with each other.\n\nIf a magnetic flux changes in a certain region in space, a rotational electric field is produced.\n\nA varying magnetic field is inseparable from an electric field.\n\nThe division of electric fields into electric and magnetic fields is a relative matter.\n\nFrom one point there is only a magnetic field in space. From another view point in addition to the magnetic field there is an electric field. \n\nThe converse is also true.\n\nIf an observer in one system of coordinates finds only an electrical field present, then an observer in another inertial system will find that both an electrical field and magnetic field exist.

The electric and magnetic vectors are perpendicular to the direction of propagation.\n\nAlso the electric and magnetic vectors are at right angles to each other.

Gee .. been a while.  If I remember correctly the magnetic field is perpendicular to the electrical field.  Thus around the two wires the magnetic fields move in the same direction and combine, producing a net attractive force.\n\nIf the currents go the opposite direction, the forces repel.\n\nSee the link below for a more detailed explanation and pictures:

ionic,the diference in electronegativity values is greater then 1.6.  the metal bonded to a non metal method is also correct

Try this. Iron when combined with other metal elements becomes non-magnetic, yet with varying of the same elements is quite attracted to the magnet.Name the divisions of the metals and explain why.

Don't read too much into this.  The simple truth is that there is no reason, this only convention.  If you want to call protons negative charges and electrons positive charges, that will have absolutely no effect on the science, just as long as you're consistent.  Conventions like this one are set up to alleviate confusion in the community, but there is no greater, cosmic purpose.\n\nYou will run into similar conventions when talking about the sign of electric current (defined as the flow of positive charge, which is counter-intuitive since the electron is conventionally negative and it is the electrons that actually move), the sign of energy differences/heat flow (positive if moving into the system from the surroundings), and several other physical quantities.

Physics does not describe magnetic monopoles;\nonly dipole with a north pole and a south pole.\nWhen you break an iron magnet, you have two magnets.\n\nTh

Accelating charges (and only accelerating) always produce magnetic fields in the space around them. So with AC current the charge carriers are contually changing direction and must hence be accelerating and so produce magnetic fields. The flux rises and falls before reversing direction with each change in current direction

False, because the binding energy increases steeply till iron and again reduces. So I would require enormous accelerators to transmute the element with Z>20.

They have full outter electron shells, so they are less reactive with other elemnets and they are all in the gas stage at room temperature. Hm, I think that's right. It's been a few years...

No\n\nThe reason this has\nnever happened is due to the source of magnetic fields:  moving electric\ncharges.  When electric charges (e.g. electrons) move in circles, they\nproduce a magnetic field.  In a piece of iron, it is very easy to line up\nthese circles, getting all the little magnets to work together as one big\nmagnet.\n\nFor each of these circles, one side is the north pole and one side is the\nsouth pole.  Since each circle has two sides, each circle has a north and a\nsouth pole.  Even the smallest possible magnets (spinning electrons) have a\nnorth and a south pole.
