Electro magnets are only magnetic when an electric current is flowing, unlike a standard magnet which is always magnetic. When the electric current is switched off, the magnetism decays away (collapses). They normally take the form of a fixed core made of soft iron surrounded by a coil of copper wire which acts as the conductor for the electric current. There is a special form of electro magnet which has a movable core instead of it being fixed and this type of electro magnet is called a solenoid. You can see large electro magnets at work at a scrap metal yard, where they are employed on a crane jib to lift and transport scrap iron and steel.
An electromagnet is that type of magnet that only acts like a magnet only when an electric current passes through it.
Under normal conditions, an electromagnet is not magnetic, but when current is passed through the electromagnet, it turns into a strong magnet. Magnet fields are generated when electricity is passed through the electromagnet.
This property can be used to selectively make a material magnetic and non magnetic.
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current
electromagnet is a magnet which remains as magnet till when electricity is passed through it.it loses its magnetized property when electricity is stopped passing through it
it is a magnet that is powered by electricity, such as the ones for picking up cars.
He was famous for proving his theory that a changing magnetic field could generate a electric field and vice versa. this made it possible for later generations to create electric generators as well as motors
Not magnetic
Magnetic: Fridge magnet Non magnetic: Milk
It non magnetic
Non magnetic!!
No, eletromagnetic waves propagate in two planes (eletro-magnetic) and can propagate in a vacuum. Water waves, on the other hand, are dependant on matter to transfer energy, making it a mechanical wave, not an eletromagnetic one.
Non mechanical waves are Eletro magnetic waves. We can devide 2 waves. 1 is mechanical waves & 2 is electromagnetic waves. For example Sound is a mechanical wave & Light is an electromagnetic wave.

magic just kidding a eletro magnet
A magnet that becomes energised when an electric current is passed through it.
Volts are the measure of Eletro motive force. (EMF)

The electro magnet is a British invention - by the scientist William Sturgeon in 1824. See related link for more details.

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.
