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.
How can the magnitude of the magnetic field be increased?
Increase the currency. Increase the size of the coil. Increase the tightness of the coil.
How do you increase the amount of current created by a generator?
You can use a transformer to increase the current. Note that this will also decrease the voltage. The total energy will not increase; it will decrease slightly, due to losses in the transformer.
What are the three ways in which the strength of induced emf in electric generator can be increased?
Increase the current, increase the windings and increase the metal core mass.
A short circuits in any system are always accompanied by a sudded?
current decrease

What are the factors that increase the magnetising force of an electromagnet?
-- diameter of the current-carrying winding around it -- number of turns of wire in the winding -- magnitude of the current in the winding -- material comprising the core of the magnet
How big is a US half dollar?
Diameter: 30.6 mm Thickness: 2.15 mm Weight (current): 11.34 gm; (40% silver): 11.5 gm; (90% silver): 12.5 gm
How do you increase current in a battery?
we can increase the current in battery by using current amplifiers or chopper's s the easy way to increase the current in battery........
Which current uk coin has a diameter of 3cm?
No current circulating British coin has a diameter of exactly 3 cm. The closest is the £2 coin with a diameter of 2.84 cm.
Does thickness of a metal affect its electrical resistance?
Metals are conductive, but are not perfect conductors and so they have some electrical resistance. How the resistance of the metal is affected by "thickness" depends on what you mean by thickness. If the electrical current has to flow through a longer piece of metal, then the resistance of the metal to electrical flow would be greater. However, if you take that same length of metal and increase the area of the metal by increasing its "thickness", then the resistance of the metal becomes less.
An increase in ocean salinity can increase what creating a current?
An increase in ocean salinity can increase density creating a convection current.
What happens if you increase the current in an electomagnet?
As current increases, the electromagnet strength will increase.
How do you make a super power full electromagnet?
-- Use greater length of wire. -- Wind it into more turns around the coil. -- Decrease the diameter of the coil. -- Increase the electrical current through the coil. Each of these actions will increase the strength of the electromagnet.
Does the magnetic field increase or decrease if the current is decreased?
An increase in an electrical current will cause magnetism to increase but a decrease in an electrical current will cause magnetism to decrease.
Does lowering resistance increase current?
Current is proportionally inverse to resistance and when the voltage is fixed, lowering resistance will increase the current
When resistance increase the current does what?
The current decreases.
