the electromagnet makes the door close when a fire alarm goes off
Cibie provides earphones. The earphones provided by Cibie gives off clear sound resolution which is what makes the item so easy to sell and to distribute.

An electromagnet makes a great door lock. The steel in the door will stay put until the electromagnet is turned off.
The strength of an electromagnet is determined by the number of windings, the current flowing through the windings, and the permeability of the core.

maybe electrical energy i don't know
I would explain phonetic sounds by telling nursery children that each letter makes a specific sound, like when we say the letter "A" it sounds like "ah". I would use visual aids like pictures or flashcards to associate each sound with a familiar word that starts with that letter. I would also encourage them to practice making the sounds themselves to help reinforce their understanding.

This is what makes a magnet an electromagnet - the ability to turn it on and off... Anyway, electromagnets can be turned off with either the help of a switch, or just by disconnecting the power supply.
For a simple copper wire around iron nail electromagnet, increasing the number of rounds the copper wire makes around the nail will increase the electromagnet's strength. Also, increasing the voltage applied(adding a battery) will increase the magnetic field.
