How does distance affect the magnetic field strength of a magnet?
If the distance between two magnets is doubled the magnetic force between them will fall to a quarter of the initial value. If the distance between two magnets is halved the magnetic force between them will increase to four times the initial value.
How does the strength of a magnetic field change with distance from a magnet How does the shape of the magnet affect the magnetic field?
Your data should have suggested that magnetic field strength decreases as distance increases. However, stronger magnets can continue to influence the direction of the compass’ needle from greater distances away.
What happens when magnets move away from each other?
If two magnets are pointing with like-poles together (a south pole to a south pole OR north to north), then stored-up energy will decrease if they move apart. So our rule says the magnets will be pushed in the direction that decreases the amount of stored-up energy. That is, they are forced apart (repelled).
What happens to the strength of the magnetic force as you separate magnets?
The force depends on the distance between the magnets. The farther apart the magnets are, the weaker the force. When the magnets are touching one another, at distance = 0, the force will be approximately equal to the magnet’s listed Pull Force, Case 1.
Why does magnetic force change with distance?
If the distance between two magnets with like poles gets smaller, then the repelling force between them will get bigger, because the force between two magnets gets stronger as they get closer together, and weaker as they get farther apart.
What affects the strength of a magnetic force field?
Factors Affecting the Strength of the Magnetic Field of an Electromagnet: Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core.
How does the magnetic field strength varies with distance?
The strength of the magnetic field decreases with distance from the wire. (For an infinite length wire the strength is inversely proportional to the distance.)
How does magnetic force work?
All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.
Where is the magnetic force the strongest on a magnet?
poles
It is strongest at the poles. So, what are magnetic poles? Magnetic poles are opposite ends of a magnet where the magnetic field is strongest.
