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

Which change will most likely increase the strength of a magnetic field produced by an electromagnet?
Add a battery
What does an eletromagnet do in a motor?
Provide amoving magnetic force field.
What can you infer about the strength of a magnetic field based upon the position of the iron filings?
The profile of the iron filings reflects that of the magnetic field. When the magnetic field is strong, the lines will be really tight (small separation) and thick (height and width). =========================
The length of a part being magnetized by passing an electric current from one end to the other affect 1 permeability 2 strength of magnetic field 3 not affect magnetic field?
Permeability
A magnet and a metal paper clip have the strongest magnetic attraction when the distance between them is?
Zero - that is, when they are touching. The strength of the magnetic force is inversely proportional to the square of the distance between the magnet and the paper clip.
How the magnetic field around a solenoid can be strengthened?
The strength of the magnetic field produced by a current carrying solenoid depends on:The number of turns - larger the number of turns, greater is the magnetism produced.The strength of the current - when current increases, magnetism also increases.Nature of 'core-material' used in making the solenoid - if we use soft-iron as a core for the solenoid, then it produces the strongest magnetism.
Will increasing the number of loops in a solenoid cause the strength of its magnetic field to decrease?
No; increasing the number of loops in a solenoid will cause the strength of its magnetic field to increase.
Which factors affect the magnetic strength of a solenoid which is carrying an electric current?
Factors affecting the magnetic field strength of a solenoid are: - length of the solenoid - diameter of the solenoid - current through the coil around the solenoid - number of turns of the coil of current around the solenoid, usually turns of wire - material in the core
Why is the strength of an electromagnet so much greater than the strength of a solenoid's magnetic field?

Why is a iron bar placed in a solenoid?
Solenoids operate by means of electro-magnetic force when a current is passed through them. Iron is easily magnetised and is the only choice for the core.
Current passing through a conductor is increased from 10 A to 15 A. This decreases the strength of the magnetic field produced by the conductor.?
No. More current will result in more magnetic field.
How could you increase the strength of a solenoid?
by increasing the number of turns of solenoid........
What is magnetic field strength?
Earth's magnetic field strength at the equator is about 30 microtesla.
If the strength of the magnetic field at B is 6 units the strength of the magnetic field at A is?
3 units
What happens to the strength of an electromagnet when the voltage in the coils of the solenoid is decreased?
The greater the current in the coil, the stronger the magnetic field will grow. Conversely, lowering the battery voltage decreases the current, weakening the field.
What do strength mean?
here strength means magnetic field strength
