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 do you call the force around a magnet?
the area of magnetic force around a magnet is called the magnetic field
What is the Force that pushes or pulls magnetic material near a magnet?
Magnetic forces are produced by the motion of charged particles such as electrons. Magnetism is one of the fundamental forces of nature.
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.
In which part of the magnet are magnetic forces strongest?
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center
A magnet and a metal paper clip have the strongest magnetic attraction when the distance between them is?
Zero - that is, when they are touching. The strength of the magnetic force is inversely proportional to the square of the distance between the magnet and the paper clip.
Where is the magnetic force the greatest on a magnet?
The magnetic force of a magnet is strongest at its poles. This is because the field lines of the magnetic field are most concentrated at the poles where they enter and leave the magnet. At the poles the magnetic field is strongest and the force is the greatest. The north pole is where the magnetic field lines enter the magnet. The south pole is where the magnetic field lines leave the magnet. The magnetic field lines are most concentrated at the poles. The magnetic force is greatest at the poles.
What is a magnetic force of a magnet called?
The magnetic force of a magnet is called magnetism.
Magnetic force decreases as distance from the magnet increases?
Yes, as the distance of the magnet increase its magnetic force decreases
Does magnetic force decrease as distance from the magnet increases?
Yes, as the distance of the magnet increase its magnetic force decreases
What is a magnetic poles?
A side where the magnetic force seems to be concentrated.
What do you call the force around a magnet?
the area of magnetic force around a magnet is called the magnetic field
What is the relationship between the distance. From the magnet and the strength of the magnetic force?
Magnetic force is inversely proportional to the square of the distance from the magnet which generates it.
How does placing a magnet near another magnet produces a magnet by?
creates magnetic force
What is the name of the force that attracts a paperclip to a magnet?
magnetic force
Where is the magnetic field concentrated in an electromagnet?
In an electromagnet, the most intense (concentrated) magnetic flux is in the core. The lines of magnetic force then radiate out from each pole in such a way as to form a closed loop between the N and S poles of the magnet. [You might want to consider why these external lines of force separate themselves from each other. - Just follow the laws of magnets.]
What is the region of a magnet force?
Magnetic Field
When The region around a magnet where the magnetic force act is the?
magnetic field
