Without poles, it's not a magnet. It's just a bar. All magnets have north and south poles.

How many poles of a bar magnet are there and where are these poles located?
Answer. Two properties of a magnet are: (i) A magnet always has two poles: north pole and south pole.
What happens to the bar magnet as it nears the U magnet the bar magnet will?
Move towards the U magnet so that the poles attach.
What happened to a bar magnet when broken in half?
Six. Every bar magnet has 2 poles. If a bar magnet is broken, each resultant piece will be a bar magnet in its own right.
WhAT ARE THE ENDS OF THE BAR MAGNET CALLED?
poles
When you break a magnet in half how many poles do the pieces have?
A bar magnet has two poles, a north and a south. When you break a bar magnet into to pieces, you create two bar magnets, each with a north and a south pole. So the total number of poles will then be four.
Which poles on a magnet will repel?
Like poles repel, opposites attract. So a N pole of one bar magnet will repel the N pole of another bar magnet. And the same applies to two S poles.
What is the distance between the two poles of bar magnet?
Magnetic equator.
What can you conclude if you place the north pole of a bar magnet near the pole of an unmarked magnet and they repel?
That you have placed the magnet towards the northern pole of the unmarked magnet. Like poles retract while opposite poles attract
Why are the poles of a bar magnet not situated at the extreme ends of the magnet?
The poles are situated at the ends of the bar magnet. The magnetic lines of force run through the magnet, emerge from one end, fold back around the length of the bar of the magnet, and curl back into the other end. The ends are the magnetic poles, and the magnetic lines of force emerge from one and re-enter the magnet at the other. You can see these lines by laying flat a piece of smooth paper over the magnet and sprinkling iron filings over the paper. Because they are light they will be easily moved into alignment by the magnetic field and will visually show the fields arrangement. (Using a piece of paper makes it easy to tidy up. Without it, the filings will stick to the magnet and be difficult to remove.)
On a bar magnet where are lines of magnetic force the greatest?
near both magnetic poles
What is a pole on a magnet?
The poles of a magnet are the ends of the core of the magnet, where the lines of force emerge. An experiment with iron filings shows the lines of force, by putting a sheet of paper over the magnet and sprinkling fine iron filings. This is an easy thing to do at home. For a bar magnet the poles will be at opposite ends. If you have two such magnets you can experiment and find that like poles repel, opposite poles attract.
What are the similarities and differences between a solenoid and a bar magnet?
DIFFERENCE: a bar magnet is a permanent magnet where as solenoid is a electromagnet so it acts as a magnet only when electricity is passed through it. SIMILARITIES: they both act as magnets and both have a similar magnetic field.
