Many objects around us contain electromagnets. They can be found in electric motors and loudspeakers. Powerful electromagnets are used as lifting magnets in scrap yards.

Middle

broken[a] between the striker’s contact and the other contact,the striker moves back, and the circuit is complete again and the cycle repeats again and again until

Conclusion

This is an OK explanation and I appreciate the inclusion of the diagram. It needs that one modification.

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.

2. ## Testing the strength of electromagnets

Make safe I must make sure that I don't leave the power pack on for too long otherwise the wires and the crocodile clips may become over heated and start to melt.

1. ## Electromagnetism - investigating what effect increasing the number of turns in a coil on ...

20 turns will hold 50 grams 40 turns I predict will therefore hold 100 grams Above is what I thought might happen when I increased the number of turns in a coil on an electromagnet. When I predicted this I did not know that twenty turns would hold fifty grams, as this was just an estimated amount.

2. ## Strength of an Electromagnet.

The number of coils will go from 5 to 60 going up in 5's. Method To start with I need wire (which I will be keeping the thickness, mass/weight all the same), an iron horse shore shape core, an electric current (volt kept the same all through the experiment), a voltmeter (to check the current stays the same)
