What creates the Earths magnetic field?
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
Where do you use magnetic field?
In a magnetic compass, electric motors, security system sensors and a whole lot more.
What is the difference between the magnetic fields of horseshoe and bar magnets?
Horseshoe magnets have a stronger magnetic field at their poles compared to bar magnets, which have a more uniform magnetic field along their length. The horseshoe shape concentrates the magnetic field lines at the poles, making them more effective for picking up magnetic materials. Bar magnets have a weaker magnetic field at their ends but are more versatile in their application.
Is the magnetic field strongest around the ends of a magnet?
No it's pretty much the whole magnet. Hope this helps :)
Is the magnetic field the strongest around the magnet ends?
No it's pretty much the whole magnet. Hope this helps :)
How does an electro-magnetic wave get its name?
Electricity and magnetism are closely related. When you pass a current through a conductor, a magnetic field is produced. In continuously changing current, a disturbance is caused in the form of a wave, in both the magnetic field and electrostatic field. Hence electro-magnetic. Examples of this wave extends across a whole spectrum, including radio waves, x-rays and light.
Do Electromagnetic waves consist of changing electric and magnetic fields?
Yes, that is the whole idea of an electromagnetic waves. A changing electric field generates a changing magnetic field; a changing magnetic field generates a changing electric field; and the two of them propagate as a wave at the speed of light.
Why is light in the electromagnetic spectrum Is light a type of electromagnetic radiation But how does that work Light is not magnetic or is it?
Part of the electromagnetic spectrum can be detected by eye, and we call that bit "light". The thing about electromagnetic radiation is that a varying magnetic field causes a (varying) electric field (that's how power stations make electric current) and a varying electric field causes a (varying) magnetic field. So electromagnetic radiation is what you get when a varying electric field creates a varying magnetic field which in turn contributes the varying electric field. The whole thing then appears as bundled varying electric and magnetic field wave system which propagates at the velocity of light, That is why it is called electromagnetic. There are no magnetic poles or electric charges in it, and it can travel through a vacuum.
Differentiative between diamagnetic paramagnetic and ferromagnetic?
Diamagnetic metals have a very weak and negative susceptibility to magnetic fields. Diamagnetic materials are slightly repelled by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Diamagnetic materials are solids with all paired electron resulting in no permanent net magnetic moment per atom. Diamagnetic properties arise from the realignment of the electron orbits under the influence of an external magnetic field. Most elements in the periodic table, including copper, silver, and gold, are diamagnetic. Paramagnetic metals have a small and positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons, and from the realignment of the electron orbits caused by the external magnetic field. Paramagnetic materials include magnesium, molybdenum, lithium, and tantalum. Ferromagnetic materials have a large and positive susceptibility to an external magnetic field. They exhibit a strong attraction to magnetic fields and are able to retain their magnetic properties after the external field has been removed. Ferromagnetic materials have some unpaired electrons so their atoms have a net magnetic moment. They get their strong magnetic properties due to the presence of magnetic domains. In these domains, large numbers of atom's moments (1012 to 1015) are aligned parallel so that the magnetic force within the domain is strong. When a ferromagnetic material is in the unmagnitized state, the domains are nearly randomly organized and the net magnetic field for the part as a whole is zero. When a magnetizing force is applied, the domains become aligned to produce a strong magnetic field within the part. Iron, nickel, and cobalt are examples of ferromagnetic materials. Components with these materials are commonly inspected using the magnetic particle method.
What are the physics behind dropping a magnet down a metal pipe?
As a magnetic field passes by a ferrous material an electric current is created locally in that material, in this case the pipe. Anytime an electric current is produced that changes with time, a magnetic field is generated. The magnetic field that the pipe produces creates a force in the opposite direction of gravity. This magnetic field created by the pipe affects the magnet falling and creates a breaking force. This whole thing is refereed to as Eddy Currents.
How does an electric coil works?
when u give supply to a coil then a current will be passed through it .naturally a magnetic field is produced around the c.c.c(current carrying conductor). when u make more turns in the same direction the whole magnetic field will be stronger than that of a wire has. andby lenz's law there will be an opposition to the changing current in a coil due to the change in magnetic field produced
Can wire be magnetized?
If it's made of a ferromagnetic material, sure. Otherwise, no, but a wire carrying a current will have a magnetic field. This is the whole concept behind electromagnets.
