Magnetic materials are notoriously hard so you will damage an ordinary hacksaw blade if you cit a bar magnet with a hacksaw (but you should eventually succeed if you do not mind dulling a few blades). An angle grinder with a metal cutting disk will work but magnetism is destroyed above the Curie temperature (about 500° C) so you should cool the magnet often as you cut through it (beware of sparks and bits flying off - wear protective clothing, ear and eye protection!).

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.


What will happen when a piece of bar magnet is broken into a few smaller pieces?

by the force of attraction in magnet their pieces will re join wd each other. All the broken pieces will become separate individual magnets.


If a bar magnet is broke in the middle and pieces are held near why do they repel did the bar magnet pieces flip poles when it broke?

sort of. magnetic fields in a bar magnet always run south to north. if you break it in half, that same S-->N direction still applies. in fact if you were to break it up into smaller & small pieces you would still have that relationship. that is to say, you wouldn't have a north only piece and a south only piece.


How many individual magnets are formed when a long bar magnet is broken into four unequal pieces?

7


What happens to a bar magnet when it is cut in half?

Each half will become its own magnet with its own north and south poles. The resulting magnets will have a weaker magnetic field compared to the original bar magnet, as some of the magnetic domain alignment will be disrupted during the cutting process.


What is the difference between a bar magnet and a electromagnet?

A bar magnet is a permanent magnet that produces a magnetic field without the need for an external power source. An electromagnet is a temporary magnet that produces a magnetic field when an electric current flows through a coil of wire. The strength of an electromagnet can be controlled by adjusting the amount of current flowing through the coil.


What shape of a permanent magnet corresponds to the magnetic field formed by a solenoid?

A solenoid typically produces a magnetic field similar to that of a bar magnet. The magnetic field lines form loops around the solenoid, making it closely resemble a bar magnet with north and south poles at either end.


Is there a scale for magnet strength?

They are bar magnet ,horse shoe magnet ,lime stone magnet.


What happens to the properties of a bar magnet if it were broken in thirds?

Each piece would become a separate magnet with its own two poles, just like the original bar magnet. Cutting a bar magnet does not eliminate its magnetic properties; each piece will still have a north and south pole.


Is bar magnet a natural magnet?

no


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.


If you cut a candy bar in half will its density change?

No, cutting a candy bar in half will not change its density. Density is a constant property of a substance, and cutting it into smaller pieces does not alter its mass or volume, which are the factors that determine density.
