To the magnetic North Pole which fluctuates in it's distance from the true pole.

I'm not sure how many types of pie there are exactly, as there is a lot and there are more and more that people keep making, but here are the ones I know of:

-Pecan

-Key lime

-Apple

-Pumpkin

-Blueberry

-Lemon Meringue

-Strawberry Rhubarb

-Banana Cream

-Boston Cream

-Walnut

-Cherry

-Blackberry

-Shoo fly pie

-Pineapple pie- is there such thing?

-Custard

-Mango

-Kumquat pie- don't know if there is such thing but I bet it would be good

-Mince Meat

-Chicken Pot Pie

-Sweet Potato Pie

That makes 20, but there is a LOT more, I know. If I find out anymore, I'll come back and edit this!

There ARE no magnetic lines of force. The magnet and iron filings demonstration causes the illusion of lines, but if you take a picture of the "lines" and replace the paper and iron filings, the "lines" will appear in a different place. But if there WERE lines of force they probably could exist in vacuum.

Yes Ofcourse ,when a curren is allowed to pass through a conductor,"IT IS BEING SURROUNDED BY MAGNETIC FIENLD"....

Because it somehow behaves as the electromagnet as per FARADAY LAW OF ELECTROMAGNETIC INDUCTION.............

it is called the thumb rule right hand curled means flux line thumb means direction of current. there will be a reversal of flux.

An electromagnet can be used a couple of ways. It can be used on the end of a crane, to pick up large pieces of metal to be moved into shredders, or restacked for transportation, crushing, etc. It can also be used to separate metal from non-metal pieces. Usually, these types of magnets are on a conveyor belt, and will cull metal from, say, plastics or other non-ferrous metals such as copper, and aluminum.

Like magnetic poles repel, unlike magnetic poles attract. So the magnetic south and magnetic north of two bar magnets will attract. Therefore, though the compass needle points towards the magnetic north, it is actually the magnetic south pole of the compass needle that is pointing towards the magnetic north.

I don't know - try putting it on scales!

If you mean the region of influence of the earth's magnetic field then its called the earth's magnetosphere

Sure. A charge in a magnetic field experiences a force.

A force acting on a mass produces acceleration.

Remember the old-style TV sets that were about 6 feet deep from front to back ?

That type of picture tube is called a 'CRT', for "cathode-ray tube'.

There's a hot wire at the back end of the picture tube that produces a cloud of

electrons. The front face of the picture tube has a high positiver voltage on it,

to attract the negative electrons to the front. On the way there, the electrons

have to go through these magnet coils that are around the neck of the picture

tube. The magnetic field inside the neck pulls the stream of electrons left and right,

up and down, left and right, and that's how they draw a picture on the front face

when they get there.

In science, field means any part of the universes that has some measurable value of a given quantity at every point.

The ancients were aware of shocks from electric fish. However the first formal study and the coining of the name "electricity" (from the Greek word for amber) was made by the English scientist William Gilbert in 1600.

The first battery was made by the Italian scientist Alessandro Volta in 1800.

The theoretical/mathematical understanding of the phenomena of electricity and magnetism (and light) was provided by the Scottish scientist James Clerk Maxwell in 1861.

Electromagnetism is the law of attraction and interaction between electric currents and magnetic fields.

A current circulating in a hollow copper coil (solenoid) produces a magnetic field equal to the permeability times the turns density times the current.

B = μ x n x I

* B is the magnetic field measured in Tesla

* μ is the relative permeability of the solenoid's core which is air in this example and have a value approximated to 1.25663706E-6

* n is the turns density which equals the number of turns divided by the solenoid length

n = N/L where L is measured in meters.

* I is the current flowing within the solenoid and measured in Amperes

The magnetic material of which the box of the refrigerator is fabricated,

such as iron or steel.

yes.magnetic field present around the conductor.
current and magnetic fields are inter related..
with current we can produce magnetic field and vice versa

The falling magnet will dislodge some air as it falls. When it hits the ground it will cause a vibration carried by the air molecules to you ear creating a bang noise. Then, depending on the force of the fall and the surface on which it lands it may, or may not crack.

Since neutrons have no charge, they are not influenced measurably by an electric field.

Electric force of repulsion.

iron colbalt and nickel

Probably not.

You need a ferromagnetic material for a magnet to stick. There are basically three elements that are ferromagnetic: Cobalt [Co]; Nickel [Ni]; & Iron [Fe] (and some esoteric ones too). If the metal alloy that has been plated with silver to make the "silver plate" has enough of these then a magnet will stick, of these, only Nickel is commonly a component of alloys that are plated but often not in concentrations that are sufficient to make it obviously magnetic.
