Should the heating element of an electric iron be made of of iron Silver or nichrome wire?
It should be made of nichrome wire because resistivity of nichrome is high.Its high resistivity causes nichrome to heat up faster, when an electrical current is passed electricity moves through the wires, givingheat to the element.hope it helped
Will a nichrome wire light up when heated?
Nichrome is a name for a nickel- chromium resistance wire, a nonmagnetic alloy of nickel and chromium. Common alloy is 80% nickel and 20% chromium, by weight. Silvery-grey in colour, corrosion resistant and has a high melting point of 1400 C (2552 F). Due to it's high resistivity and resistance to oxidation at high temperatures, it's widely used in heating elements, such as in hair dryers, electric ovens and toasters. Typically, Nichrome is wound in wire coils to a certain electrical resistance, and current passed through to produce heat. For heating, resistance wire must be stable in air when hot. Nichrome wire forms a protective layer of chromium oxide. Kimber :)
How do you use NiChrome wire?
One use for NiChrome wire is to make electrical heating elements.
Why is a copper wire in a closed circuit does not get heated but a nichrome does?
this is because copper wire offers no resistance and thus electric current passes through them without producing heat energy whereas in nichrome offers a large resistance and thus the mechanical energy of the drifting electrons changes to heat energy rapidly .
What has more resistance a nichrome wire or a copper wire?
Nichrome wire has such high resistance that it is used to convert electrical energy into heat. Many heating elements are made from nichrome. Copper wire has the best conductivity, for the price, of any metal.

How electric geyser works?
A electric Geyser has a Element screwed in the side of the inner water container, with the heated side submerged in water, parallel to the element (sometimes center) is a thermostat unit to control the temperature by switching the element off once the desired temperature has been reached. The element itself is made with nichrome wire, which is a resistive wire, When a Electric current is passed through the nichrome wire the resistance of the wire restricts the current causing a pressure of electrons and protons (as water builds pressure in a hose pipe when the end is restricted) and intern creates heat as a byproduct.

What shape is the magnetic field produced when current is passed through wire?
CIRCULAR
How is electricity used in an electric iron?
Electric iron contains a resistance wire (nichrome) . When a current of I amp is passed through the wire, electrical energy equal to I^2Rt (joules) is produced which is entirely converted to heat. This is a unique characteristic of resistance element as compared to capacitors or inductors where there is no power dissipation. Here R = resistance of the wire in ohms and t= the amount of time that the current passes through the resistance wire. The metal base at the bottom of the electric iron is thus heated up.
Is copper wire is magnetic?
it produces a magnetic field. i think that if current is passed through the wire it can attract pieces of iron

What is made by passing an electric current through coils of wire?
An electro magnet is created when a current is passed through a coil of wire. This effect is the main operation of how an electrical solenoid operates.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
