How can a non magnetic nail be magnetised?
Typically you can magnetize iron or steel by exposing it to a strong magnetic field. Common "ceramic" magnets may not be strong enough, but you may need a strong rare earth magnet or a strong electro magnet.
How ferroelectrics are different from ordinary dielectrics?
ferroelectrics have strong magnetic field and also magnetic susceptibility & permeability value are strong (>1) but dielectric have feebly magnetic field & it have lesser value.
Earth magnet what?
Earth's magnetic field (and the surface magnetic field) is approximately a magnetic dipole, with the magnetic field South pole near the Earth's geographic north pole (see Magnetic North Pole) and the other magnetic field N pole near the Earth's geographic south pole (see Magnetic South Pole). This makes the compass usable for navigation. The cause of the field can be explained by dynamo theory. A magnetic field extends infinitely, though it weakens with distance from its source. The Earth's magnetic field, also called the geomagnetic field, which effectively extends several tens of thousands of kilometres into space, forms the Earth's magnetosphere. A paleomagnetic study of Australian red dacite and pillow basalt has estimated the magnetic field to be at least 3.5 billion years old.
How do you make a sentence for magnetic field?
The magnetic field of the Earth protects us from cosmic radiation.
How the compass works?
The Earth has a magnetic field approximately like a magnetic dipole, with the magnetic field S pole near the Earth's geographic north pole and the other magnetic field N pole near the Earth's geographic south pole. A compass can determining direction relative to the Earth's magnetic poles by using a magnetized pointer (usually marked on the North end) which is pivoting free to align itself with Earth's magnetic field.
Is mars magnetic field strong or weak?
no mars magnetic field is not strong because it is far away from the sun than earth.
Earth has a strong magnetic field and is essentially a big magnet Where are the magnetic fields strongest on Earth?
Algeria haha
Why does mercury have a strong magnetic field?
That's easy because it doesn't. Mercury's magnetic field is only about 1% that of Earth.
What is the layer in which the magnetic field of the Earth is produced?
The outer liquid core produces the strong magnetic field of the Earth, through the dynamo effect.
Does sun have magnetic energy?
no, only our earth has the magnectic energy The Sun has a very strong magnetic field.
Why does Earth Have a strong magnetic field?
Because it has a molten metallic core and a fast rotation.
Does Uruguay have a magnetic field?
The earth as a single object has a magnetic field. If Uruguay is part of the earth, it shares the earth's magnetic field.
How is the earth's magnetic field created according to the film?
by bipolar winds that overcame what used to be a large second earth, which then forged with our earth to create a single earth with a strong magnetic field. it is solely coincidence that it does what it does and Obama used to be white

If the earth rotated more slowly would you expect it to have as strong a magnetic field?
No it would probably weaken. The Earth's magnetic field is due to a combination of two factors: Earth's relatively high iron content and Earth's relatively high rotation speed. If you reduced either factor you should expect the magnetic field's strength to be reduced.

Why Auroras do not happened near equator?
The auroras that are experienced near the polar regions occur because of the strength of the earth's magnetic field. The magnetic field is not very strong at the equator.
