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 else can I help you with?
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.
At the centre of a bar magnet magnetism is?
At the center of a bar magnet, the magnetic field lines converge and form a strong magnetic field. This region is referred to as the magnetic core of the magnet, where the magnetic strength is at its maximum. This is why the bar magnet's strongest magnetic force is typically concentrated in its center.
Where is the magnetic force is greatest?
The magnetic force is strongest at the poles of a magnet, where the magnetic field lines are most concentrated and closer together.
What part of a magnet is concentrated?
it isn't, a magnet contains electrons and neutrons which connect to the electrons and neutrons in metal!
A magnetic pole is the part of a magnet where the magnetic effect is weakest?
A magnetic pole is where the magnetic effect is greatest.
What locationis the strongest megnetic force on a magnet are the?
The strongest magnetic force on a magnet is typically at the poles, where the magnetic field lines are most concentrated and directed. The force diminishes as you move away from the poles towards the center of the magnet.
Where is the pull of a magnet strongest at?
The pull of the magnet is strongest at the poles.
What area of a magnet has the strongest magnetic effect?
The area of a magnet with the strongest magnetic effect is typically the poles, specifically the tips of the magnet where the magnetic field lines are most concentrated and the magnetic force is strongest.
What part of a magnet is greatest?
The poles of a magnet are the parts where its magnetic field is strongest. The north and south poles are the regions where the magnetic force is concentrated and where other magnetic materials are most affected.
Magnetic forces are the weakest at the poles of a mangnet.?
This statement is incorrect. Magnetic forces are strongest at the poles of a magnet, where the magnetic field lines are most concentrated. The strength of the magnetic force decreases as you move away from the poles towards the center of the magnet.
Where there is magnitude of the magnetic field around a permanent magnet greatest?
The magnitude of the magnetic field around a permanent magnet is greatest at the poles of the magnet. This is where the magnetic field lines are most concentrated and where the magnetic force is strongest.
What is a magnetic force of a magnet called?
The magnetic force of a magnet is called magnetism.
