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.
Yes, each half still has magnetic properties.
Use a magnet to remove the iron, a filter or screen to remove the sand, and a still to remove the salt.
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.
we can find the poles of a ring magnet by tieing thread along the circumference of it and suspend it with a torsionless string then it will allign itself according to earth magnetic field
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.
melt a magnet and mold it like a ring...hehehe...
No, the metal ring cannot if it is made out of copper.
No, the magnet will not fall as a freely falling object when dropped toward a conducting ring. The magnet will experience resistance due to electromagnetic induction as it moves towards the conducting ring, which will slow down its descent. This is known as magnetic braking.
No. While electricity and magnetism are closely connected, the poles of a magnet no not correspond with electrical charges.
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?
atomic structure
Inside a magnet, there are tiny particles called atoms that have their own magnetic fields. These atoms align in the same direction, creating a magnetic field that gives the magnet its magnetic properties.
ear rings a sit is made of material but in case of magnet it is a stone so ear ring is a good conductor.So be ware of wearing a ear ring ear rings a sit is made of material but in case of magnet it is a stone so ear ring is a good conductor.So be ware of wearing a ear ring
If it sticks to a magnet it's not gold.
