because huge asteroids get pulled into Saturn's gravitational field
the answer is the iron of magnetic field so that it can cause magnetic field... iron.
ferromagnetism - permanent magnets, with N and S pole, all the atoms are aligned and 'spin' the same way so the magnetic field is strong in one direction paramagnetism - an object becomes temporarily magnetic when a field is applied and the resulting field is parallel to the applied field diamagetism - a temporary magnetism opposite to that of the applied field
Yes, you can demagnetize a magnet by subjecting it to high temperatures, hammering it, or exposing it to a strong magnetic field in the opposite direction.
When one refers to the strength of a magnetic field, they're usually referring to the scalar magnitude of the magnetic field vector, so no.
Yes. Though it is not designed to be so. Anything with electricity running through it is magnetic. People are more concerned with how strong is this magnetic field generated by the electricity running through it. Go read up on electro-magnetism.
The high permeability of ferromagnetic materials is due to the alignment of magnetic domains within the material, which allows for easy movement of magnetic flux. This alignment creates a strong magnetic response to an applied magnetic field, leading to high magnetic permeability.
A magnetic field is a region around a magnet or a current-carrying wire where a magnetic force can act on other magnets or moving charges. The magnetic force is the force exerted by a magnetic field on a magnetic object or a moving charge. So, the magnetic field is what allows the magnetic force to act on objects within its influence.
magnets?A magnetic field surounds the entire Earth, so figure it out from this hint.

The rotor of an alternator need a DC voltage applied to it to generate a magnetic field, this magnetic field will generate the AC power in the AC windings.The AVR(Automatic Voltage Regulator) is regulating this DC voltage so that the magnetic field is strong enough to maintain the output AC voltage. As soon as more current is drawn from the output, this output voltage will drop and a stronger magnetic field is needed to sustain the output voltage, so the AVR step up the exiting voltage to get a stronger magnetic field to compensate for the voltage loss in the AC windings.
Copper is not inherently magnetic, so it cannot be magnetized in the traditional sense like iron or steel. However, you can induce a magnetic field in copper temporarily by placing it in a strong magnetic field, passing an electric current through it, or using special techniques like the Faraday effect.
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.
