What does solenoid do?
work as the current carrying coil-of wire on and acts like magnet when conductor flows
What is soleniod?
A current-carrying coil of wire that acts like a magnet when a current passes through it.
How is a solenoid similar to a magnet?
A solenoid acts like a magnet when an electrical current is sent through the coil. A permanent magnet is magnetic all the time. Therefore, they are similar when both act like a magnet, but not when the solenoid is turned off.
Why is an electromagnet considered to be a temporary magnet?
An electromagnet acts as a magnet only while electricity is passing through the coil. Once the electricity is turned off, the electromagnet ceases being a magnet. Electromagnets are much used in scrapyards. Attached to a crane, metal is picked up and deposited into railway wagons, or road haulage vehicles, to be sent for recycling.
What are the similarities and differences between a solenoid and a bar magnet?
DIFFERENCE: a bar magnet is a permanent magnet where as solenoid is a electromagnet so it acts as a magnet only when electricity is passed through it. SIMILARITIES: they both act as magnets and both have a similar magnetic field.

Why do speaker have magnet?
The magnet is part of the 'motor' of the sub. The coil inside the magnet has alternating current running through it. The coil acts as an electromagnet and pulls itself up or pushes itself down moving the cone of the speaker. The bigger the magnet, the stronger the magnetic field inside the speaker where the coil is.
What is an eletro magnetic?
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.
When biased correctly a zener diode acts as?
a diode and it has a constant voltage across it ANSWER: acts as a voltage regulator if enough current flows to create a breakdown voltage.
The space around a magnet where the force of the magnet acts is a?
electromagnet

Is an entire magnetic domain acts like a bar magnet with a north and a south pole?
yes because it acts on the magnet
Does earth acts as magnet?
yes
