What types of magnets are produced by running current through a soft iron core?
electromagnets
What types of magnets are temporary?
Electromagnets. They are generally required to loose their magnetism, as soon as the power is removed. This is done by using a soft iron core or laminated plates.
How do you use a sentence about electromagnets with an iron bar and copper coil?
The student tested his theory using electromagnets, an iron bar, and a piece of copper coil.
How are electromagnets formed?
A magnet consisting essentially of a coil of insulated wire wrapped around a soft iron core that is magnetized only when current flows through the wire.
What are 5 facts about electromagnets?
1 a nuke uses electromagnets so does not fall apart they use it to keep the iron shell on and so it does not fall over and does not explode randomly.
What types of magnets are produced by running current through a soft iron core?
electromagnets
Does an iron box use electromagnets?
no there is no use of electromagnets in iron box
Why Soft Iron is suitable for preparing electromagnets?
soft iron B-H curve area is very high and hysteresis loss is proportional to it frequency or no of loop cycles per sec and area of loop so hysteresis loss increases in soft iron as electro magnet
What is a magnet that can turn on and off what is it made of?
Electromagnets, they are usually made of a iron core and a warping of copper.
What type of magnet is used to lift heavy cars?
a big one electromagnets they are made of soft iron and have a large coil wound around them they are powered by a heavy current and do not retain the magnetism when power removed
How are both permanent magnets and electromagnets used in a motor?
They both are strong and are made of iron and steel.
What are electromagnets made from?
you get a magnetic maerial (mainly iron nail) and wrap copper wire around it and attach a baterie to the copper wire and there you have it, an electromagnet
What types of magnets are temporary?

Explain why a magnet can attract pins but not matches?
A magnet is made of 'Soft' Iron. A pin has steel (iron) in it. A match does NOT have iron in it.
What do electromagnets attract?
Unlike normal magnets, electromagnets attract just someof the alloys that contain iron, such as steel and iron, but not all of them. Electromagnets do not attract aluminium, copper, titanium,brass, bronze, tin, nickel, platinum, gold, silver, lead or pewter.Contrary to some opinions, electromagnets cannot attract cardboard.See also the related question.
