What will increase the strength of the magnetic field around the wire?

The strength of a magnetic field produced by a current carrying wire increases proportionately with the current through the wire, and it dies off as the distance from the wire decreases.
To increase the magnetic field around a coil you would either increase the current running through it (by increasing the voltage and/or using a less resistive wire), increase the number of windings, or wind the coil more tightly (bring the windings closer together).
The latter solution doesn't increase the overall magnetic flux produced, but it does make the coil more compact so the flux "leaks" less.

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.
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.
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)
Why does more coils make an electromagnet stronger?
The illustration on the HowStuffWorks website is probably the easiest to understand. As you add coils to the electromagnet you have more and more magnetic field traveling in a certain vector (depending on which way current is flowing). It's much like a lot of physics...as you add horses to a plow the force is increased. As you add coils to an electromagnet the magnetic field increases. As I said, check out this link for better understanding. http://science.howstuffworks.com/electromagnet4.htm\ A wire with an electric current passing through it, generates a magnetic field around it, this is a simple electromagnet. The strength of magnetic field generated is proportional to the amount of current. if we were to increase the number of coils the strength of the magnetic field would increase, also increasing the strength of the magnet
What is magnetic field strength measured in?
Gauss
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.
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.
What is the limit for magnetic field developed for a DC machine?
The magnetic field used in machines is quantified in terms of its flux density (symbol: B), expressed in teslas. The flux density is established by the magnetic field strength (H), expressed in amperes per metre, set up in the field windings.As the magnetic field strength increases, the flux density increases until it reaches saturation. This is the point when the magnetic domains within the magnetic circuit are all aligned. At this point, any further increase in magnetic field strength will fail to increase the flux density.So saturation of the magnetic circuit limits the flux density of the field.
What is magnetic field strength?
Earth's magnetic field strength at the equator is about 30 microtesla.
Which change will most likely increase the strength of a magnetic field produced by an electromagnet?
Add a battery
If the strength of the magnetic field at B is 6 units the strength of the magnetic field at A is?
3 units
How does the strength of the magnetic field around a wire change if the current in the wire is increased from 0.25 A to 1.75 A?
According to Ampere's Law, the strength of the magnetic field around a long, straight wire carrying current is directly proportional to the current and inversely proportional to the distance from the wire at which it is measured. Assuming fixed distance from the wire (meaning that you're measuring in the same place), if you increase the current by 1.75/.25= 7 times, you will also increase the magnetic field by 7 times.
What is the effect of adding more coils of wire to an electromagnetic?
Increasing the coils will increase the strength of the magnetic field.
Is magnetic field strength a vector quantity?
When one refers to the strength of a magnetic field, they're usually referring to the scalar magnitude of the magnetic field vector, so no.
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)
