Magnetism
Magnetism is simply an abstraction that people use for the changes in electromagnetic force created by the motion of electric charges. There are different types of magnetism that include electromagnetism, ferromagnetism, paramagnetism, and diamagnetism. To learn more and share your knowledge of magnetism and its types, ask and answer questions here.

Can magnets attract through wax paper?
Yes, magnets can still attract through wax paper because wax paper is a thin material that does not significantly block the magnetic field. The magnetic force can penetrate through the wax paper to attract objects on the other side.
Can a magnet attract through paper?
Magnets attract iron but not paper because paper has no magnetism.
Is a soil magnetic material or a non magnetic material?
it generally depends on the soil content~if it is rich in iron or some other magnetic metals it will magnetize but if it don't it won't..
soil is non-magnetic but iron filings in it are magnetic
What is the magnetic charge of the South Pole?
Negative is the current magnetic charge of the Earth's South Pole.
But such has not always been the situation. Scientists suggest that the charge changed from positive to the current negative about a million years ago. At the same time, the North Pole's magnetic charge changed from negative to its current positive.
AnswerWe do not describe a magnetic pole as a 'charge', and the terms 'positive' and 'negative' are not applied to magnets. Magnetic poles are described as being 'north' and 'south', whereas electric charges are described as being 'positive' or 'negative'.
Having said this, it should be mentioned that people involved with magneto therapy do describe magnetic poles as being 'positive' and 'negative', but this is a pseudoscience and much of its terminology is nonsense.
What is a thin flat circular magnet?
A thin flat circular magnet is a magnet that is disk-shaped with a small thickness. It is commonly used in applications where a strong magnetic field is needed in a compact form, such as in sensors, magnetic switches, or small electric motors.
Can a magnet be used to separate small pieces of metal from a mixture of metal?
Yes, a magnet can be used to separate small pieces of ferromagnetic metal from a mixture of metal. The magnet will attract the ferromagnetic metal pieces, allowing them to be easily separated from the rest of the mixture.
Does Judaism have only one sect?
No, Judaism has multiple sects including Orthodox, Conservative, Reform, and Reconstructionist, each with its own beliefs and practices. These sects vary in their interpretations of Jewish law, tradition, and religious observance.
How can you tell if a piece of iron is magnetized or neutral?
If the piece of metal is a magnet it will attract another piece of iron. You should be able to feel this attraction as the two become very close. It's magnetic field can be "seen"( that is the effect) by placing iron filings on a piece of glass and place the magnet beneath the glass. Otherwise it is not a magnet.
Why are some 2ps not magnetic?
Some 2p coins are not magnetic because they are made of different metals such as copper, bronze, or brass that do not contain magnetic properties. These coins may be composed of alloys or combinations of metals that do not exhibit magnetic properties like iron or steel.
How are magnetic domains are arranged in a magnetic material?
Magnetic domains in a magnetic material are regions where atomic magnetic moments align in a common direction. These domains can be arranged in various ways, including in a random manner, aligned in specific directions, or in a more organized pattern depending on the material and external magnetic field. The overall magnetic properties of the material depend on the size, orientation, and interactions between these domains.
How are magnet fields and electric fields alike?
Both act only on charged particles (ions, protons, or electrons). ?However, an electric field (which generates an ELECTRIC FORCE) acts on a particle in the same direction as the field, given by the equation:
F(vector) = q*E(vector)
The resulting force vector is in the same direction as the field vector (for positive charges).
A magnetic field generates a force ONLY on a MOVING charge, and ONLY if the charge is moving non-parallel to the magnetic field:
F(vector) = q*v(vector) x B(vector)
Because of the cross-product, the magnetic force is a direction perpendicular to the velocity and magnetic field vectors (use the right hand rule to figure out the direction of magnetic force). ?The particle will still have momentum from its initial velocity, so an applied magnetic field will (pretty much) always make the particle move in a curved path.
Why can't we use a permanent magnet in a scrap yard?
You need to use an electromagnet in a scrap yard so that you can let go of the pieces of scrap that you pick up. A permanent magnet would not allow you to let go.
What two kinds of electron motion are important in determining the magnetic property of a material?
The two main types of electron motion that are important in determining the magnetic property of a material are spin motion and orbital motion. Spin motion refers to the intrinsic angular momentum of an electron, giving rise to its magnetic moment, while orbital motion refers to the movement of electrons around the nucleus within an atom, contributing to the overall magnetic behavior of the material.
Do magnetic underlays affect peacemakers?
Magnetic underlays affect on pacemakers are theorized currently. There are theories that they do have an effect on blood supply if used while there are some theories that do not support this concept. I would suggest consulting with your physician.
Are Indian coins attracted to a magnet?
Most Indian coins are not attracted to a magnet because they are made of non-magnetic materials such as copper, nickel, or steel. However, some coins may contain a small amount of iron or ferrous material which could make them weakly attracted to a magnet.
What does magnetic field lines denotes?
a line to represent the direction of a region around a magnetic material or a moving electric charge within which the force of magnetism acts.
A2. Perhaps better describes as lines of magnetic force. These are lines of equal intensity between the North and South pole of a magnet. They are similarly charged, hence they repel each other. They extend arbitrarily far into space if allowed to, and will eventually form a sphere.
These lines of magnetic force are that along which your compass aligns itself at your locale.
Why are nano dots better than zen magnets?
Better Product Quality - The first reason that Nanodots are superior to zen magnets is that they have a higher quality product. Nanodots are engineered to a precise size and shape, which allows you to build large and complex structures. They actually built the Guinness World Reccord Magnetic Sculpture. The World Record weighs over 320 kg and contains over 550,000 magnets.
Nanodots will last forever because of their good quality. And unlike zen magnets, Nanodots come in 4 colours, 2 of which are coated in real silver and real gold!
Also, if you check out www.thenanodots.com - they offer you tutorials on how to build lots of cool creations using Nanodots. They offer better support to customers and people who love the product.
Nanodots are also offering accessories such as the Nanopad! The Nanopad is a perfect accessory for Nanodots as it provides the ideal surface for building with Nanodots and playing Nanodots games on. And the Nanopad features a dot counter to help build with Nanodots quickly and easily.
Enjoy Nanodots.
What would occur if two magnets were placed with their north poles end to end?
If you placed two magnets with their north poles end to end they would repel each other.
Why does stroking a metal makes it magnetic?
When a metal is stroked repeatedly in the same direction, the atoms within the metal align in the same direction, creating a magnetic field. This process is known as magnetization, and it can make the metal magnetic.
How can you make an iron nail into a magnet?
Use a D battery, connect the negative and positive to separate copper wire. On the other end of the wire, wrap it around an iron nail (make sure there is space between the wire) and there you go!!
What happens to the domains in a piece of iron when it becomes magnetised?
The iron automatically divides into domains separately. It does not exist in a state when magnetization occurs in the same direction, in the entire material. This is to minimize its internal energy.
How do the iron filings behave when sprinkled over the bar or horseshoe magnet?
The iron filings align along the magnetic field lines when sprinkled over a bar or horseshoe magnet. This creates a visual representation of the magnetic field around the magnet. The filings cluster at the poles of the magnet where the magnetic field is strongest.
Is magnetic field conservative field?
it is not a conservative feild....it is a non conservative feild
What is painting pictures with magnets?
Magnetic painting involves using magnetic particles in the paint that respond to a magnetic field to create patterns or images. By manipulating the magnetic field, users can control the movement and arrangement of the particles to form unique designs.
What happens to the bar magnet as it nears the U magnet the bar magnet will?
Move towards the U magnet so that the poles attach.
