What material should you use for an electromagnet?
Soft iron core
What types of magnets are produced by running current through a soft iron core?
electromagnets
Why does the soft iron core increases the strength of magnetic field?
Iron core (usually soft iron core) is a highly ferromagnetic material. Ferromagnetic materials allows (and attracts) the magnetic field lines to pass through it. When such a material is used in the electromagnet, the magnetic field lines passing through it increases, thereby, the strength of the electromagnet increases. So my friend, I hope you are satisfied with the answer.
What are the 4 ways to make an electromagnet stronger?
Use: More turns of wire A higher current A larger core area A core material with high permeability (soft iron instead of air for example)
What is the purpose of the soft iron core used in making electromagnet?
The purpose is to enhance the magnetic field - to make it stronger - compared to just using air.
If a soft iron core is Inserted into a solenoid will the strength of magnetic field produced by it change?
It has been found that if a soft iron rod called core is placed inside a solenoid, then the strength of the magnetic field becomes very large because the iron core is magnetized by induction The core of the electromagnet must be of soft iron because soft iron loses all of its magnetism when current in the coil is switched off or stopped
Would a wooden core work to make a stronger magnet?
No, the core has to be a soft iron core.
What material should you use for an electromagnet?
Soft iron core
Why air coil with soft iron core inductance is greater then air coil laminated steel core?
Soft iron has a greater permeability than steel. BTW, the only reason for laminations is to reduce eddy currents in the core. It has no effect on permeability or inductance.
Why is soft iron named as soft iron?
Soft iron does not retain magnetism. It can be magnetised and demagnetised quickly and easily. Used as a core for transformers. 'Soft' probably relates to it's submission, when exposed to magnetism. It 'gives in' without too much fuss.
Electromagnetic-induction device usually has which of the following materials in its core?
soft iron
Inserting a soft iron core into a coil has what effect on the inductance of a coil?
increase inductance
What types of magnets are produced by running current through a soft iron core?
electromagnets
What is the state of matter of all the earths layers?
crust = solid mantle = solid soft enough to flow though outer core = liquid iron inner core = solid iron
What types of magnets are produced by runing electric current through a soft iron core?
your moma
What makes soft iron a suitable core for transformers?
Low hysterisis loss and high permeability
Why is the core of a moving coil galvanometer made of soft iron?
The term galvanometer is used to refer to a meter which can measure small currents, usually in the mA (10-3A) or mA (10-6A) range. When a soft iron core is used, the magnetic field lines tend to crowd through the core. It is because soft iron core is ferromagnetic in nature. As a result, the strength of the magnetic field due to the field magnet increases, which in turn increases the sensitivity of the galvanometer.
