How do you identify the polarities in round magnet?
BhageshKumarSeri
You can identify the polarities in a round magnet by placing another magnet next to it. If they repel they have the same polarity and if they are attracted the polarity is the same.

What are 5 types of artificial magnets and state their uses?
Bar magnet, ball ended magnet, cylindrical magnet,horse shoe magnet, round magnet
Can a round magnet produce electricity if it's rotating?
The shape of the magnet is unimportant. Any moving magnet can induce a voltage in a wire. Or any changing magnetic field. If the magnet rotates, its magnetic field will change, so yes.
Do the same polarities repel?
Yes.
Is the magnetic field of an electromagnet different to a bar magnet?
The magnetic domains in a refrigerator magnet are laid down in parallel strips. They are also re-curved back on themselves so that the back side of the magnet has both north and south poles. If you put two refrigerator magnets back-to-back and move them around a little, it won't take long for you to "feel" the strips of magnetism. The common bar magnet have two simple poles at the ends.
How can you convert a soft iron into a magnet?
By winding a coil of copper wire round it, and passing an electrical current through the wire.
Can you make a magnet float with another magnet of the opposite polarity?
No, opposite polarities attract, alike polarities repel.
How can a compass be used to detect Earth's magnetic field?
A compass needle is actually a weak magnet. Because in magnetism opposite polarities attract while like polarities repel, the needle's north pole seeks the earth's south pole and vice versa.
Is there a scale for magnet strength?
They are bar magnet ,horse shoe magnet ,lime stone magnet.
Where is the field round a magnet strong?
The field strengthens as you get closer to the surface of the magnet.

What are ring magnet properties?
They are round. And they are magnetic. Without a specification for the magnet nothing more can be assumed.
How do you identify the north and south pole of a magnet?
Use a compass. It's needle points to the south pole of a magnet.
What is the procedure to identify metals?
