  1. The Efficiency of an Electric Motor.

    To test this I have plotted the power recorded against the voltage I recorded squared. This should give me a straight line in the form In which y=Power recorded, m=1/R, x=V2, c=O since when V=0 P=0 I have also plotted a how the power should vary with respect to the voltage squared for use as a comparison.

    conclusion, from these I agree that I was wrong in my prediction to state that as the number of coils doubled so did the weight the electromagnet could hold. From the results I was gaining I could easily see that the numbers were not following the pattern I had predicted E.g.)

  1. Strength of an Electromagnet.

    one end of the nail near the compass, you will find that it has a much larger effect on the compass. In fact, the nail behaves just like a bar magnet. A simple electromagnet However, the magnet exists only when the current is flowing from the battery.

  2. Testing the strength of electromagnets

    Power Pack- To provide a current to flow through the wires. Connector wires- To connect the power pack to the coiling wire. Paper clips- Paper clips are magnetic so they are a good method to test the strength of an electromagnet.
