What else can I help you with?
A metal bar or rod used in stirring fire?
It is known as a Poker.
Is bending a metal wire a chemial or phyiscal change?
Physical. The metal wire is still a metal wire after the change.
How can a metal bar be made to expand in all directions?
Heating the metal bar evenly will cause it to expand in all directions. This is known as isotropic expansion, where the material expands uniformly in all dimensions. Heating allows the atoms in the metal to move more freely, causing the entire metal bar to expand uniformly.
How do you wire a wire to a wire?
If you are connecting 120 volts, you connect the black wire to the breaker, white wire to the neutral bar, and ground wire to the ground bar. If you are connecting 240 volts connect the black & white wires to the breaker, & ground wire to the ground bar.
How to electrify metal?
Not sure what you mean by electrify. You can make an electromagnet by wrapping a bar of iron (not steel) with a wire winding and passing a current through it.
What colour wire goes to the breaker using 12-2 wire?
For a typical 12-2 wire, the black wire is the "hot" wire that connects to the breaker, the white wire is the neutral wire that connects to the neutral bus bar, and the bare copper wire is the ground wire that connects to the ground bus bar in the circuit panel.
What is needed to produce an elcetromagnet?
A power source, stripped(?) wires, a bar of metal, and probably a switch. create a coiled section in the wire with many loops. connect all components except the metal bar in series. insert the bar inside the coil. now whenever the current is runnind it should have magnetic properties.
What wire of an appliance connects its metal base to the ground through the household wiring?
The green or green/yellow wire in an appliance connects its metal base to the ground through the household wiring. This wire is known as the ground wire and is an essential safety feature to prevent electric shocks in case of a fault.
What is the metal used in wire?
In most cases, copper is the metal used in wire.
What is thicker 28 or 30 gauge?
The thickness of metal wire is inversely proportional to the guage number of the metal wire. So 28 guage metal wire is thicker than 30 guage metal wire.
What materials can be used to create an electromagnet?
Take a small iron cylinder or length of bar, wrap a load of insulated wire around it several times, and then pass a current through the wire by connecting both ends of the wire to a battery. If you cant find a metal bar, maybe a thick steel kitchen utensil or piece of cutlery will do.
How do you magnetise a iron bar?
If you wrap a length of wire around the iron bar then pass a current through the wire, the bar will become magnetised.
