The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by
the motion of charges
. Two objects containing charge with the same direction of motion have a magnetic attraction force between them.
Which action will cause the magnetic force to push?
The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by
the motion of charges
. Two objects containing charge with the same direction of motion have a magnetic attraction force between them.
What forces occur when two magnets are brought close together?
When two magnets are brought close together,
their magnetic fields interact
. You can see how they interact in the Figure below. The lines of force of north and south poles attract each other whereas those of two north poles repel each other.
What happens when you push 2 magnets together?
When two magnets are brought together,
the opposite poles will attract one another, but the like poles will repel one another
. This is similar to electric charges. Like charges repel, and unlike charges attract. Since a free hanging magnet will always face north, magnets have long been used for finding direction.
What happens to the strength of the magnetic force when magnets are moved closer together?
For example, closer you are to the Earth,
stronger the force
. Similarly, a magnet sets up a magnetic field in its surrounding space in which it magnetically affects any other magnetic material. The strength is represented by the density of the magnetic field lines.
What is the difference between electric force and magnetic force?
The electric force
acts between all charged particles
, whether or not they’re moving. The magnetic force acts between moving charged particles. This means that every charged particle gives off an electric field, whether or not it’s moving.
Which location has the greatest magnetic force?
The magnetic field of a bar magnet is strongest at
either pole of the magnet
. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
What does it mean when two magnets repel?
When two like-poles point together,
the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up
. So the magnets will push apart (repel). … It’s only when you hold unlike-poles together (a north pointing to a south) that magnets stick together (they are attracted).
What happen when the materials were placed near the magnet?
Answer. Answer: 1) When two magnets are brought near each other,
like poles repel
; opposite poles attract. 2) When a magnet is brought near a piece of iron, the iron also gets attracted to the magnet, and it acquires the same ability to attract other pieces of iron.
Where will you find the maximum magnetic force in a magnet?
The pole of a magnet
is the area which has the greatest magnetic field strength in a given direction. Each pole is either north facing or south facing.
Is a magnets push or pull stronger?
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.
What shape of magnet is strongest?
The strongest part of a magnet is concentrated at the poles. That is why
a horseshoe shape
is considered the strongest and can be very useful to create if you want to lift heavy objects or want to make a bar magnet stronger.
Are 2 magnets stronger than 1?
Yes, stacking multiple magnets together can make them stronger. Two or more magnets stacked together
will exhibit nearly the same strength as a single magnet
of the combined size.
What is the relationship between magnetic force and distance?
Magnetic force obeys an inverse square law with distance. The equation for magnetic force is similar to Coulomb’s Law (if you are familiar with it). But the key point is that
the force is inversely proportional to the distance squared
(i.e. it obeys an inverse square law with distance).
What factors affect the force of attraction between magnets?
- Distance between magnet and adhesive surface.
- b) Direction of the force:
- Material of the object of magnetic attraction:
- Surface area of the object of magnetic attraction:
- Thickness of the object of magnetic attraction:
What is the relationship between the distance and strength of the magnetic force?
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.
