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.
How can you strengthen a solenoid's magnetic field?
Think of the four C's- Add more Coils- Add an iron Core- Add a stronger Current- Make the coils Closer
Can an electromagnets strength be changed?
The more electricity the more powerful the magnetic field. Increase the voltage, which for the given resistance of the coil, will also increase the current and the magnetic field.
What are some ways to increase the magnetic field strength?
Increase the size of the magnet. Increase the current passing through the wires (electromagnets) Increase the number of coils of the wire (electromagnets)
What are four factors that can be varied to change the strength of two magnets?
increase the current in the solenoid add more loops of wire to the solenoid,wind the coils of the solenoid closer together, use a stronger ferromagnetic material for the core. I hope this answered better than the last rude person.

No; increasing the number of loops in a solenoid will cause the strength of its magnetic field to increase.
How could you increase the strength of a solenoid?
by increasing the number of turns of solenoid........
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 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.

Why is the strength of an electromagnet so much greater than the strength of a solenoid's magnetic field?

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.
What would increase the strength of the magnetic field?
increasing the number of coils
Do the induced voltage increase in a transformer when the magnetic field strength increase?
Yes, the more voltage you put in the more you get out. If the transformer is a 2 - 1 ratio and you put 240 in you get 120 out and when you put 480 in you get 240 out. Magnetic field strength and voltage have a direct relationship. +++ The field strength is actually a function of current, although as you say, increasing the voltage will increase the current hence the magnetic field.
Can an electromagnets strength be changed?
The more electricity the more powerful the magnetic field. Increase the voltage, which for the given resistance of the coil, will also increase the current and the magnetic field.
Which change will most likely increase the strength of a magnetic field produced by an electromagnet?
Add a battery
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
