Do electricity meters consume electricity?
they do consume a LITTLE peice of electricity probably about 1p a month 12p a year
What is the difference between magnets and electromagnet?
an electromagnet is a magnet which is activated by electricity and it ceases to be a magnet once the electric supply is stopped whereas a magnet is a natural magnet which does not need electricity and continues to be a magnet whether it is supplied by electricity or not.
What kind of magnet can attract steel and iron due to electricity?
electromagnet

What is an electromgnet?
An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.
What are the advantages and disadvantage's of an electromagnet?
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.
