Yes, power is needed: When a current is sent through the coil of wire wrapped round a central core of iron, the iron becomes an electro-magnet.
Yes, electricity meters consume a small amount of electricity to power their internal components such as digital displays and communication modules. This small amount of electricity consumption is accounted for in your overall energy usage.
An electromagnet can attract steel and iron due to electricity. When an electric current flows through the coil of wire in an electromagnet, it creates a magnetic field that can attract ferromagnetic materials like steel and iron. The strength of the magnetic field can be controlled by adjusting the amount of electric current flowing through the electromagnet.
No. but he used an electromagnet to make discoveries about electricity.

An electromagnet is only magnetic while current is flowing through the coils. A permanent magnet is always magnetic, and does not need electricity. An example of an electromagnet at work is in a metal scrape yard, where a large electromagnet is used by a crane operator to lift ferrous metals into a crusher (scrapped cars, for instance). The metal drops into the crusher when the electricity is switched off by the crane operator. Therefore, they are only really similar when both are magnetised.
Yes
When the electricity supplying an electromagnet is switched off, the magnetic field produced by the electromagnet disappears. This means that the electromagnet loses its magnetic properties and no longer attracts or repels magnetic materials.
electromagnet can be acquired when electricity is passed through the soft iron piece.

Electricity and magnecity
It is called an electromagnet.
It doesn produce electricity. It uses electricity and shows magnetic properties.
The flow of electricity affects the strength and functionality of an electromagnet by determining the magnetic field produced. More electricity flow increases the strength of the magnetic field, making the electromagnet stronger and more effective in attracting or repelling objects.
an electromagnet requires electricity and you will have to pay for it. permanent magnets are always on and you can change the strength of it.
no because you need electricity to turn it on
When you turn on electricity in an electromagnet, it creates a magnetic field around the coil of wire. This magnetic field allows the electromagnet to attract or repel other magnetic objects depending on the polarity of the current flowing through the coil.
