When you loop the wire with a current it will?
increase the strenght of the magnetic field. :)
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.
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 the build with a shorter wire give more brighter than the longer wire?
Because the shorter wire gives less resistance than the longer one and more electricity per inch is distributed to the shorter wire.
How do you increase the force exerted on a current carrying coil placed in a magnetic field?
Since the magnitude of force on a wire is I*L*B*sinθ, then you can increase the current, or increase the magnetic field, or adjust the angle so that it is per pendicular to the coil wires. You can increase the lenght (increase the number of turns).
What happens to the electric current when the wire is made smaller?
If wire delivering a certain amount of current is made narrower, the resistance of the wire will increase. This will limit current, and the wire will warm up some. If the wire is made shorter, resistance will decrease. The electrical codes have well published limits on the amount of current different types of wire can carry.
What happens to the current carrying ability of a wire when the temperature increases?
the current will increase
When a wire is made smaller the resistance increases. what happens to electric current?
increase
What are some ways to increase the magnetic field around a wire?
There's only one way to do that: Increase the current (amperes) in the wire.
When you loop the wire with a current it will?
increase the strenght of the magnetic field. :)
Two ways to increase the strength of an electromagnet?
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.
How could you make your electromagnet stronger?
there are 3 ways,*changing the number of coils of wire,*changing the current in the wire,*changing the material used for the core.sidenote - i just saw this answer and its perfect, really. simple and just the three points i needed for homework!how could you make them stronger
When a wire is smaller the resistance increases What happens to the electrical current?
increase
If You wrap a wire around a piece of iron. If you slowly increase the strength of an electric current flowing through the wire you would expect .?
The temperature of the wire will increase and eventually like the "straw breaking the camel's back" the wire will fail if you apply enough current. It is like exceeding the current in a fuse, the wire essentially disintegrates.
What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
Does increasing current on a wire increase the magnetic force acting on it?
Only if the wire is running perpendicular to a magnetic field.
Does a light bulb light up faster the shorter the wire?
Yes but as the current travels at the speed of light it would have to be thousands of miles shorter to detect a difference
