They are round. And they are magnetic.
Without a specification for the magnet nothing more can be assumed.
A permanent magnet may become unmagnetized because a shock it will have.
Use a magnet to remove the iron, a filter or screen to remove the sand, and a still to remove the salt.
Yes, each half still has magnetic properties.
A permanent magnet (in contrast to an electromagnet).
Not exactly. All pieces of the magnet retain their ferrous properties, but if they were (for example) dropped, then the shock of the fall could potentially make them lose a bit of magnetism. Extreme temperature changes and high power electric discharges could also decrease the power of the magnet.
Nothing happens, except that now you have two magnets. The poles of a magnet are not actually localized at the two ends of the magnet but are inherent to the magnetic properties of the magnet. As the magnetic properties are not altered by a modification of the magnet such as cutting it in half, there will be no effect on the poles of the magnet.
i believe the speed record for RPM's is held by a diametric ring magnet.
Permanent magnets do not lose their magnetic ability. Temporary magnets, however, gain magnetic properties when they are touched or moved by a permanent magnet. The properties of a temporary magnet dissipates over time after the permanent magnet is removed.
No, all materials do not have magnetic property. But if an iron is rubbed with a natural magnet,gets the properties of magnet.
A magnet has both a South pole and a North pole. The magnetic properties of a magnet come from the alignment of electrons inside of the magnet. The North pole of a magnet will repel another North pole, but attract a South pole, and vice versa.
No. While electricity and magnetism are closely connected, the poles of a magnet no not correspond with electrical charges.
You can tell if a ring is real gold or not by putting it near a magnet. If the ring is attracted to the magnet it is not real gold, real gold is not magnetic at all.
No, the metal ring cannot if it is made out of copper.
melt a magnet and mold it like a ring...hehehe...
A magnet is an object that is magnetic if it displays magnetic properties. Think of it like this; If bar magnet attracts a piece of metal towards it, it is using magnetism (fluxuations in electric current) and therefore the magnet can be said to have magnetic properties.
Anyone can reply this questions?
