When you rotate the paperclip and make contact with the second thumbtack you close and Battery v paperclips the circuit, current flows through the circuit and lights up the bulb Figure 3. Also, place any other available extra batteries 6V, 12V, etc.
Fourth, try using your fingernail to slide each turn of the coil up against the previous turn, while pulling the wire tight with your other hand.
If you have enough stripped wire, you can also wrap the wire around the tips of the alligator clips.
This will make it more difficult to keep the turns tightly packed against each other, as they will tend to fall into the threads of the bolt. The current running through the circuit will heat up the wire. To locate the magnetic field of the electromagnet, direct students to move the compass in a circle around the electromagnet, paying attention to the direction that the compass points see Figure 3.
In insulators, such as the wire covering, electrons do not move easily, so you can work with electricity safely. First, it is important to have the starting point of your coil taped firmly in place to the iron core.
My finished coils are coming uncoiled because the tape holding the end in place is falling off.
Procedure Gather materials and make copies of the Building an Electromagnet Worksheet. Spring-tension wood or plastic clothespin Number 22 insulated copper bell wire Small block of wood Nail, thumbtacks, and paper clip 3-volt flashlight bulb How to Build the Circuit: A higher voltage translates to a greater current, and with more current, the electromagnet becomes stronger.
When the circuit switch is open Figure 2 current does not flow to the bulb. To continue making the electromagnet, connect the ends of the coiled wire to each end of the battery using the rubber band to hold the wires in place see Figure 4.
Dangle the paperclip near the coil again. Look at the answer to the question "How do I know when the wire is stripped?
You can also try stripping the insulation off a longer section of the magnet wire tail and folding over the end of the tail to make it thicker. Once you have finished making the turns on your coil, it is also important to tape the ending point of the coil firmly to the iron core. In other words, the electromagnet will not work if something is preventing electric current from flowing from the battery through the wire.
One end of each clip lead should be connected to one of the terminals of the battery one lead to each terminaland the other end of each lead should be clipped to the stripped part of the magnet wire one lead to each end of the wire.

• A battery pack • Some paper clips 2. There are four different settings on the battery pack. They are labeled V, V, V and V.
The “V” stands for volts. A volt is a unit used to measure the amount of electricity in Record the number of paperclips picked up by each electromagnet for each try. After you. Battery Holders, Clips & Contacts are available at Mouser Electronics.

Intro: Electric Coil Motor Masco G This is how to make an electric coil motor with a battery, coil, paperclips, a magnet, sand paper, and elastics! The battery pack seemingly grows smaller and more powerful with every version of the V-series vacuums. The V10's battery provides an impressive full hour of vacuuming per charge.
