∙ 9y agoUsually such magnets are made out of iron. If that is the case, I would expect its density to be similar to that of iron (approximately 7900 kg/m3).

How a solenoid may be used to demagnatise a bar magnet?
Heating a bar magnet with solenoid demagnatise it.
What happens to a bar magnet when it is cut in half?
The bar magnet becomes two smaller barn magnets.
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.
What are 5 types of artificial magnets and state their uses?
Bar magnet, ball ended magnet, cylindrical magnet,horse shoe magnet, round magnet
How does volume of a chocolate bar affect the density?
Density is equal to M/V. So, if the volume of the chocolate bar increases, the density decreases, and if the volume of the chocolate bar decreases, the density increases. This is called an inverse relation.
How do you calculate the magnetic dipole moment of a bar magnet?
The strength of a magnet can be determined by measuring its flux density (B) which is expressed in teslas. The flux density will vary according to where relative to the magnet it is being measured. The instrument for doing this is a flux-density meter (which was called a 'gaussmeter' - 'gauss' being an obsolete unit of measurement for flux density, from the cgsA metric system).
Is a bar magnet magnetic?
A bar magnet is a magnet of rectangular shape with a north and and south end, which are sometimes coloured different colours to indicate which end is which.
Is there a scale for magnet strength?
They are bar magnet ,horse shoe magnet ,lime stone magnet.
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.
The use of bar magnet in chemistry?
The magnet bar is used for stirring solutions.
How is an electromagnet different a bar magnet?
a electromagnet is bigger than a bar magnet
Is a magnet?
Yes, a bar magnet is magnetic.
How do you draw a small bar magnet?
because it is easy to convey from small bar magnet
What type of magnet attracts to iron but not for a long time?
Bar magnet. Because a bar magnet is strong to iron..... Or that's what we did in class.....
What does a magnet field in a solenoid resemble?
a bar magnet
Is magnet magnetic?
Yes, a bar magnet is magnetic.
