Build a Simple Electric Motor! | Science Project
An electric motor uses the attracting and repelling properties of magnets to create motion. An electric motor contains two magnets; in this science project, you will use a permanent magnet (also called a fixed or static magnet) and a temporary magnet. The temporary magnet is also called an electromagnet.A permanent magnet is surrounded by a …
Galvanic Cell
lab report experiment electrochemistry galvanic cell introduction: chemical reactions involving the transfer of electrons from one reactant to another are. ... The cell potential, E cell, which is a measure of the voltage that the battery can provide, is calculated from the half-cell reduction potentials:
Simple Motor
Next, assemble the motor as shown in Figure 3. The safety pins are attached to the battery with the rubber band and the wire coil ends go through the holes in the ends of the safety pins. Here, we used a little …

How to Make a Homopolar Motor | STEM Activity
When the wire touches the top of the battery and the magnet (which is touching the bottom of the battery) at the same time, electrical current flows through the wire. This electrical current passes through the magnetic field created by the magnet. This results in a force that pushes on the wire, causing it to spin around the battery.
How to Make a Homemade Battery Science Experiment
How to make a homemade battery. All you need are a few simple materials to try this homemade battery: Pennies (at least 5 if you would like to use your batteries to light up an LED); Aluminum foil (only a small amount, about a foot (~1/3 meter) of length is needed); Paper towels (about 1 square); Vinegar (I used distilled white vinegar, …
Take Charge: a global battery experiment Investigation 1 …
In the Take charge: global battery experiment learners can explore batteries and the important role they play in a sustainable future by making their own. There are two …
Experiment 6
There are two 9-volt batteries already installed in the photodiode housing. To check the batteries, you can use a voltmeter to measure the voltage between the output ground terminal and each battery test terminal. The battery test points are located on the side panel. You should replace the batteries if the voltage is less than 6 volts.
Required Practical: Investigating EMF & Internal Resistance
This will prevent the internal resistance of the battery or cell from changing during the experiment; Random Errors: Only use fairly new cells otherwise the e.m.f. and internal resistance of run-down batteries can vary during the experiment; Wait for the reading on the voltmeter and ammeter to stabilise (stop fluctuating) before recording the ...

the end of the experiment. The rated battery capacity is the total charge the battery can give up. Unfortunately, only about 85% of this charge is actually useable in our experiments. Therefore, you will need to multiply the rated battery capacity by 0.85 to find the useable charge in this experiment. As the battery gets weaker, the
260 11-1 EXPERIMENT 11 THE POTENTIOMETER I.
in this experiment, so that the function of each component can easily be seen and understood. In the general schematic diagram in section IV, AB is a length of uniform wire eleven meters long. The battery 1, called the working battery, maintains a constant current I from A to B. The resistor R1 controls the amount of current in the wire, ...
