At the centre of a bar magnet magnetism is?
zero
What advantage does an electromagnet have against a bar magnet?
With an electromagnet, the magnetism can be turned on and off according to the whim or need of the operator.
If a magnet bar were heated would it change its magnetic field?
Initially, no. At a certain temperature the bar would suddenly lose its magnetism. This temperature is known as the Curie point of the material. If the magnetism of the bar came from an external source - a solenoid or a permanent magnet - the field would return to its original strength as soon as the bar cooled below the Curie point. If the bar had been itself a permanent magnet almost all the field would stay gone until the bar was re-magnetised by an external field.
How does the shape of magnets affect its magnetism?
hello,a magnet has several poles for every atom of a magnet has n,s poles.a bar magnet has two poles ,a ring magnet has no poles.so if a shape is different the atoms are arranged differenrtly and thus it affects its magnetism

At the centre of a bar magnet magnetism is?

How could heating a bar magnet reduce its magnetism?
Heating a bar magnet could reduce its magnetism because the heat, by raising the energy level in the metal, disorients the atoms, which disrupts the magnetism.
What is keeper and its use in magnetism?
A keeper is a iron or a steel bar that is used to retain the strength of magnet.
What advantage does an electromagnet have against a bar magnet?
With an electromagnet, the magnetism can be turned on and off according to the whim or need of the operator.
Why is magnetism induced into an iron bar placed near a magnet?
A magnetic field induces an electric current. Hence, by placing the iron bar close to the magnet, a current is induced; and so we are, in effect, creating an electromagnet.

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.....
Can magnetism pass through fruit juice?
Magnetism CAN pass through fruit juice. If you were to use a bar magnet on the table attracting another magnet on the other side, it would still attract. Magnetic studs are a good example of magnetism because they can stick/ connect together even through the flap of the ear.

How is an electro magnet different from a bar magnet?
An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.

What is the difference between magnet and magnetic and magnatism?
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.
