Who invented the eletro magnet?
The electro magnet is a British invention - by the scientist William Sturgeon in 1824. See related link for more details.
What is polarity definition for kids?
opposites attracting, like a magnet.
Volts are a mesurement of what characteristic of electricity?
Volts are the measure of Eletro motive force. (EMF)
Is magnet is a good conductor of electricity?
Conductor of electricity is sort of the definition of a magnet. Magnets conduct electrical fields; it is what makes them magnets, in very simple terms.
Can a magnet not be magnetic?
if it truly is a magnet, than no. however, you can demagnetize a magnet by dropping it or hitting it really hard to rearrange the domains within the magnet. Domains are the regions within a magnet that have particles that are either arranged so that the poles are attracted to each other or randomly arranged so that the particles are not magnetized at all. so if it is a magnet... it probably will be magnetic unless you take your anger out on it or something.
Definition of a magnet?
A magnet is an object that produces a magnetic field, which can attract or repel other materials that are capable of being magnetized. Magnets have two poles – a north pole and a south pole – which exhibit different magnetic properties.
How does an alarm bell work?
An alarm bell works by using electromagnets to create a magnetic field that causes a metal hammer to strike the bell, producing a loud ringing sound. When the alarm is triggered, an electrical current is sent through the system, causing the hammer to move back and forth and ring the bell.
Definition of temporary magnet?
A temporary magnet is a material that can be easily magnetized but loses its magnetization quickly when the external magnetic field is removed. These types of magnets are often made from soft magnetic materials such as iron or steel. Temporary magnets are commonly used in applications where magnetism is required momentarily or can be easily changed.
How is a electromagnet diffrent then a permanent magnet?
An electromagnet is a temporary magnet that only produces a magnetic field when an electric current is flowing through it, while a permanent magnet retains its magnetism without needing an external electric current. Additionally, the strength of an electromagnet can be easily adjusted by changing the amount of current flowing through it, while the strength of a permanent magnet is fixed.
What is the scientific definition of magnetism?
magnetism is a strange force from the center of the earth attracting every single magnet on the earth, it also acts as a compass to a magnet. if you take a magnet tie it to a string it will go north direction and it also act as a very concentrated metal meaning it can attract on its own.
How do wires make a fan turn?
Wires carry current to the fan from the electrical circuits of the building it is in. Inside the fan motor wires are wound in a particular fashion to make a coil. When any voltage is applied to such a wound coil, it generates an electro magnetic field. When any eletro magnet is placed near to this field, it experience a force, which is what makes the fan rotate.
Name a suitable finish for ferrous?
It is a word that stands alone. Definition; containing iron. Also if it is a ferrous material a magnet will stick to it.
