Magnetism

It doesn't matter if two south or two north poles meet, the will create a sort-of-force-field around that pole. For the south pole, it is attracted to north poles and averted from its own kind. For north, vice versa.

Whilst it may seem that since the magnetic field of the horse shoe magnet is responsible for the force between the magnet and the paperclip, it has to be noted that without the paperclip the magnet while retaining it's magnetic field exerts no force, because there is nothing for it to pull on.

A simple example lets take both our magnet and paperclip to the very back end of the universe, somewhere hypothetical where the only force allowed is magnetism (assume gravity no longer exists out here, and with that weight/mass also don't exist. Weight being how much gravity pulls you down onto the weighing scales. So for this experiment the magnet and paperclip "weigh" the exact same 0.00 pounds).

1 Take the paperclip and allow it to float in space.
2 Take the Magnet and hold it in your hand.
3 As the paperclip comes into the field of the magnet, it moves towards the magnet.
Now you didn't move and the magnet didn't move, but the paperclip did. The magnet attracted the paperclip.
Proof that the magnet is the one exerting the force, right?

Lets repeat the experiment but with a slight change.

1 Take the magnet and allow it to float in space.
2 Take the paperclip and hold it in your hand.
3 As the paperclip comes into the magnetic field of the magnet, the magnet moves towards the paperclip.
Again you didn't move, and this time the paperclip didn't move. This time the paperclip attracted the magnet.


Might seem kind of strange now, but not for long.
Here's the thing: 1 thing is certain, if the magnet and paperclip are close together they will try to attach to each other, however,
If the magnet isn't there, nothing happens to the paperclip.
If the paperclip isn't there, nothing happens to the magnet.

From this you can take that without the other, neither object has any force, but when they are near enough together they both act on each other with the same force. Equal and opposite forces to be exact (they pull together) .
Stay with me.
On earth gravity effects the magnet so it never appears to move, it's heavier than a paperclip and so every time it will appear that the paperclip moved.
But back at our hypothetical space experiment we know that it doesn't matter which object isn't allowed to move, if they are near to each other they attract each other equally. I believe the term is they move relative to each other.

Lets repeat the experiment one more time with one more slight change:
1 Take the paperclip and allow it to float in space.
2 Take the magnet and allow it to float in space.
3 Leave them close enough to start attracting each other.

Which one moves now?

Answer is at the bottom, don't cheat, think about it.


If you would Prefer a more maths orientated proof rather than abstract theory, you can always add this question to the Math section.

But to be honest physics is more fun if you try to imagine it.

Good luck.




A: They both move towards each other.

When two like poles are placed one on top of the other, they repel each other due to their magnetic fields. This repulsion force causes the magnets to float or levitate above each other without direct contact. This effect is known as magnetic levitation.

according to the ampere's law . magnetic field is strongest in a loop or a plane. and about toroid the magnetic is strongest in the coil where the wire is rotated around it . Magnetic field is minimum inside and outside the toroid.

A magnet is any material or object that produces a magnetic field. This magnetic field is responsible for the property of a magnet: a force that pulls on other ferromagnetic materials and attracts or repels other magnets.

North Seeking Pole

They don't, but we're starting to get annoyed. Why do people keep asking us Mormons about magnets? They're great, they stick to metal, they hang things on the fridge... whats the big deal? I don't know... someone started asking Mormons about magnets and we don't know why.

The metals iron, cobalt, and a few nonmagnetic elements (copper as a example, is not by nature magnetic; however many such elements can be attracted to magnetic fields with proper tweaking of the magnetic fields) there is a book published by Lindsay publications that explains. it may be out of print but it is worth a shot.

The magnet in a fan is typically located inside the motor. It is used in conjunction with coils of wire to create a magnetic field that drives the rotation of the fan blades.

Yes, the strength of an electromagnet can be easily controlled by adjusting the amount of current passing through the coil or by varying the number of turns in the coil. This allows for flexibility in its applications and makes it a versatile tool in various industries.

Not all lamps have magnets. Some lamps may have magnetic components for specific functions, such as attachment to metal surfaces or adjusting the positioning of the lamp.

Conductive plasma moves through the core of the sun because of convection. Localized magnetic fields created by the rotation of the sun create higher pressure without an increase in density. The magnetic field rises relative to the plasma until it reaches the outer edge of the sun. There it creates coronal loops and sunspots

A solenoid typically produces a magnetic field similar to that of a bar magnet. The magnetic field lines form loops around the solenoid, making it closely resemble a bar magnet with north and south poles at either end.

Magnetic separation can be used to separate components that are attracted to a magnet from those that are not. For example, separating iron from a mixture of iron and sulfur or separating magnetic materials from non-magnetic materials.

Six. Every bar magnet has 2 poles. If a bar magnet is broken, each resultant piece will be a bar magnet in its own right.

The name given to the four-point compass is a "cardinal compass." It consists of the four primary directions: north, south, east, and west.

Many things are magnetic, though in varying degrees, especially special rocks called magnets. Magma, lava underneath the surface of the earth, is highly magnetic, as lava often comes out in special areas on the surface forming a visible magnetic field. Humans are made from soil/dirt, and we have the same minerals in us as the earth does, and since the earth is magnetic, so are we, and scientists have proven that recently. They have found that we have ultramicroscopic minerals in our heads or in our brains that are magnetic, though they don't work the same way as the magnets in animals function. Animals navigate, especially during migration, due to the magnetic field of the earth, like a compass, and God designed them just for that. Also, you can make a makeshift compass by finding a small piece of light metal wire and rubbing it on your head to get static electricity. Now that it is magnetized, place it on a leaf in a pool of water, and it will align like a compass does! All thanks to Bear Grylls and his show of Man vs. Wild on Discovery channel!

U.S. paper money and coin money are both magnetic. They both have magnetic properties, but normal magnets rarely affect them. Mostly the stronger neodymium magnets can pull/affect them. The magnetic part of a U.S. note is near the corners where most the ink is at.

Maybe. Monopoles are theoretical. This has been a question for some time, and just recently, monopoles have been discovered on the subatomic level. As of yet, they cannot be turned into the magnet that you and I imagine, but with only one pole due to their unique crystaline structure.

No, slate rock is typically not attracted to a magnet because it is composed mainly of minerals like clay and quartz, which are not magnetic. Magnetic properties in rocks are usually found in those containing iron minerals, such as magnetite.

Photons are neutral particles that do not carry electric charge, so they do not interact directly with electric or magnetic fields. As a result, photons do not experience deflection when passing through these fields. However, the presence of an electric or magnetic field can still affect the path of charged particles, such as electrons, that interact with these fields.

If you eat a piece of metal you will be fine IF YOU EAT A MAGNET YOU will be fine but if you eat BOTHor eat 2 magnets, go to the emergency dept. of your nearest hospital ASAP and say that you swallowed (number of magnets)magnets

when magnets are kept loose their magnetic power becomes weak. therefore a non magnetic substance should be kept in between of two magnets while storing them. so that there is no continuous attraction or repulsion between them.

High coercivity in permanent magnets ensures that they can maintain their magnetization in the presence of external magnetic fields, making them stable and reliable for long-term use. This property also allows the magnetic material to resist demagnetization, ensuring that the magnet retains its magnetic properties over time.
