Is you true the magnetic field around an electromagnet can be made stronger by increasing current or decreasing the number of coils around the iron core?

No, you is false. Increasing current does it, but the number of turns in the coil
also must increase if you want to increase the magnetic field that way.

What will increasing the electric current to an electromagnet do to its magnetism?
An increasing electric current moving into an electromagnet will become stronger in its magnetism. As the atoms align the increasing magnetism will stop at one point, making the electromagnet as strong as it can be.
Which has a stronger magnetic field a solenoid or a electromagnet?
A solenoid is an electromagnet An electromagnet is a solenoid with an iron core
What is the significanse of increasing the number of turns on an electromagnetic coil?
As you increase the number of coils around an electromagnet, the magnetic field around the electromagnet gets stronger. As the electromagnet gets stronger it able to generate or convert more electricity and therefore this increases the efficiency rate of the transformer and hence the transformer is able to convert the voltages passing through it at a higher rate.
Is an electromagnet made of a coiled wire and a metal bolt stronger than one made with a wire alone?
Yes. An Iron core electromagnet has a stronger magnetic field then a coil. The magnetic flux is condensed and travels through the iron core with little resistance, while air provides much greater resistance.
How can you strengthen an electromagnet?
make an electromagnet stronger by doing these things: * wrapping the coil around an iron core * adding more turns to the coil * increasing the current flowing through the coil.
What effect does increasing the number of coils have on an electromagnet?
Adding more coils will make the magnetic field stronger. Magnetic field increases.
How can the magnetic field strength of an electromagnet be reduced?
Either increasing the size of the current (in amps) or the number of turns of wire wrapped around the core will make a stronger magnet. A larger current will make a stronger magnet (up until too much makes the wire melt!). Increasing the voltage forces more current through the electromagnet.
In an electromagnet the magnetic force increase as increase?
Adding more coils will make the magnetic field stronger. Magnetic field increases.
How the magnetic field of an electromagnet defends on the current and the number of coils?
The magnetic field of an electromagnet is directly proportional to both the current passing through its coils and the number of coils. Increasing either the current or the number of coils will result in a stronger magnetic field, while decreasing them will weaken the magnetic field. This relationship is described by Ampere's law and the concept of magnetic flux.
Why does the strength of the electromagnet increase from the coils?
The electromagnet is made stronger in proportion to the current given. Refer to the link provided for more information.AnswerWhen current passes through the coil of wire surrounding the core of an electromagnet, it acts to align the magnetic domains within that core. Once all the domains have been aligned, the electromagnet has reached 'saturation' and is as strong as it can get. So the strength of an electromagnet is NOT proportional to its magnetising current.
How do you make a electromagnet stronger?
For a simple copper wire around iron nail electromagnet, increasing the number of rounds the copper wire makes around the nail will increase the electromagnet's strength. Also, increasing the voltage applied(adding a battery) will increase the magnetic field.
What will increasing the electric current to an electromagnet do to its magnetism?
An increasing electric current moving into an electromagnet will become stronger in its magnetism. As the atoms align the increasing magnetism will stop at one point, making the electromagnet as strong as it can be.
How can you make an electromagnet's pulling force stronger?
An electromagnet's pulling force can be made stronger by introducing iron core in it.It increases the magnetic pull.
Which has a stronger magnetic field a solenoid or a electromagnet?
A solenoid is an electromagnet An electromagnet is a solenoid with an iron core
How does the number of wraps of wire affect the strength of an electromagnet?
The more turns of wire in an electromagnet the stronger the magnetic field.
What is the significanse of increasing the number of turns on an electromagnetic coil?
As you increase the number of coils around an electromagnet, the magnetic field around the electromagnet gets stronger. As the electromagnet gets stronger it able to generate or convert more electricity and therefore this increases the efficiency rate of the transformer and hence the transformer is able to convert the voltages passing through it at a higher rate.
What effect does increasing the current have on solenoid?
it will produce a stronger magnetic field.
