To make a solenoid, you need a hollow cylinder, a battery and lots of conducting wire. The wire must be wound dozens of times around the cylinder, with both ends connected to a battery. This allows the current to flow, replicating the effect of a bar magnet.Know More
Determine the size of your solenoid, and arrange for materials accordingly. For a hollow cylinder, arrange for something similar to the cardboard of a toilet roll. Length of the conducting wire should be adequate for three to four dozen winds around the cylinder. Get a battery of an appropriate voltage. In this case, a 5-volt should work fine.
Wind the conducting wire in tight, close packing around the cylinder around 40 to 50 times. The ends of the wire should be left loose to connect to the battery.
Attach one end of the wire to the positive and one end to the negative terminal of the battery. To test the solenoid, lower a piece of conducting metal or a magnet into the cylinder. Due to the induced magnetic field of the solenoid, the metal piece or magnet should be seen moving inside the cylinder.
Duracell batteries, like many other types of alkaline and zinc-carbon cells, contain three major components: an anode, a cathode and an electrolyte. The anode is a mixture of powdered zinc and potassium hydroxide, the latter of which acts as the electrolyte to facilitate energy transfer.Full Answer >
According to the MIT School of Engineering, a battery provides an electrical charge due to the chemical reactions that take place inside it once it is connected into an electrical circuit. When a circuit connects the positive and negative poles, the anode and cathode inside the battery react with the electrolyte medium separating the two, producing a flow of electrons. This creates an electrical current and provides power.Full Answer >
In the Unites States, the black wire is the live wire, while the white wire is the neutral wire and the copper or green wire is the earthed wire, which is also called the ground wire. The color coding of electric wires is unique to the U.S.Full Answer >
A wire ampacity table is a chart displaying the electrical amp rating carried by specific wire types and gauge sizes. Amperage is a measure of the electrical current flowing through a circuit, which is measured in amps. Proper wire size must meet specific amp limits.Full Answer >
