Does vinegar affect the magnetic pull of a magnet?
No. A magnet is a material that produces a magnetic field. The MF is invisible and is responsible for the magnet's force that pulls on ferromagnetic materials such as iron. It attracts or repels other metals.
What mixture can be separated using a magnet?
Mixture of metallic and non-metallic substances can be separated using magnet. For example - mixture of same and iron powder.
Why does iron attract to magnet?
Magnet are objects which have an electromagnetic force. It attracts iron and other metals which have the property of being induced by a magnets effect and repels other magnets.
Where is the maximum magnetic force concentrated in a horse shoe magnet?
The correct answer depends upon the quality of the magnet and the quality of the iron that it is attracted to. In general terms, the holding force will be approximately 280 lbs. of force for each square inch of surface area that is between the magnet and the iron. The force is calculated as follows. The mks formula for force is F=B²A/2µ where F is in newtons, B in Tesla, A in sq. meters, and µ is the permeability of air which is 4·pi·1E-7. Then, considering the fact that good quality iron saturates at about B=2.2 Tesla, and 1 sq.in. is = 6.45E-4 sq.meters and plugging this into the eqution gives a force of about 1242 newtons or 279 lbs. If the horse shoe magnet is holding the iron at each end of the magnet then the force will double if lifting is exactly balanced at each end. The above assumes very good surface contact between magnet and iron. Practical holding forces may be lower which can be approximated by lowering the value of B to something like 1.7 or so. dbm 7/16/09
What kind of substance attract magnet?
a magnet Actually named magnetite, but it is a natural magnet.
Does a magnet need to touch the paper clips to excert and attractive force?
You need to do the experiment. If the magnet is strong enough, metal (steel, iron) will jump to the magnet (or pull the magnet towards it).

Can you give me a short phrase for magnet?
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet. This property is the force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.
How do the iron filings behave when sprinkled over the bar or horseshoe magnet?
spread out from one pole and curve around to the other
Why people can't fly in the air like people fly in space?
On Earth we experience this thing called gravity, which is a force that pulls us towards the center of the Earth. Pretty much like a magnet pulls iron towards it. In space, people experience something called free-falling, or zero gravity. And if there's no force pulling you in any particular direction it's possible to float in mid-air, or simply push off to travel in any desired direction.
What can a student do to increase the force of attraction of a magnet on an iron?
ADD MORE IRON
What does a megnet do?
A magnet attracts other metal objects to it. This is done by combining the following materials: iron, boron, and neodymium. These materials make a magnet, and a magnet can also be made by rapping a copper wire around iron and running electricity through it, making an electromagnet.
IRON FILLINGS SCATTERED AROUND A MAGNET WILL BE MOST STRONGLY DRAWN TOWARDS what part of the magnet?
The poles.
Why only iron attracted towards magnet and not the sand?
Because iron is the useful material, not sand.
Why is Fe attracted towards the magnet?
Because iron is a ferromagnetic metal.
What mixture can be separated using a magnet?
Mixture of metallic and non-metallic substances can be separated using magnet. For example - mixture of same and iron powder.
Do the non-contact force of magnetism pulls objects that contain iron?
I have no clue
