    For every action there is an equal and opposite reaction

    This isn't really a homework question but it is something that I have been learning about out of school and this thought just popped into my head: According to Newtons Third Law: "For evry action there is an equal and opposite reaction". Now if you take a Jet engine, It works on the fact...

    Understanding the Relationship Between Current and Strength of an Electromagnet

    Ok, so I measure the difference between the Apparent mass according to the weighing scales when there is no current through the electromagnet, to when there is a certain current. Is this ok?

    Circuit diagram symbol for an electromagnet

    Is there a circuit diagram symbol for an electromagnet? Am I correct in thinking that it is a line with a coil going round it? I have looked all over the web, and cannot find confirmation of this. Thanks, Iceman123

    Understanding the Relationship Between Current and Strength of an Electromagnet

    On my graph I am thinking about plotting the difference between the mass of the c-core a when there is no current flowing through the electromagnet, and the mass of the c-core when there is a certain current flowing through the electromagnet (for example, the mass of the c-core when there was no...

    Understanding the Relationship Between Current and Strength of an Electromagnet

    Thanks for all of the answers they are helping a lot. Also, could someone tell me if I have finally got my head round the mass and weight thing. Weight is the force exerted upon something by gravity. And mass is the amount of matter in an object. These are directly proportional. Is this right?

    Understanding the Relationship Between Current and Strength of an Electromagnet

    Its probably me that got it the wrong way round, that's a good help, so thank-you. How can I link weight to the mass, so that I can write about in my report? Would it be OK to state the conversion between grams and Newtons, or should I explain some more, in which case, I will need help.

    Understanding the Relationship Between Current and Strength of an Electromagnet

    Hey there, I am studying the effect of current on the strength of an electromagnet for my GCSE assessed practial. I set up the experiment with an iron c-core on a set of scales, and a electromagnet above, in theory, I should be able to see the weight of the c-core go down as it gets lifted off...
