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.

  1. The Efficiency of an Electric Motor.

    See Diagram 3: For Diagram of Apparatus used Experimental Method: I will supply the joule meter with a constant voltage and I will time how long it takes to record energy of 10J. From this information I will be able to compare the energy I put in to the joule

  2. Testing the strength of electromagnets

    I must keep the coils evenly spaced and tight because from my preliminary test I found that the tighter the coils the more paper clips were picked up. I am also going to test to see if any paper clips are picked up if I don't have any coils of wire around my iron core.

  1. Investigating Electromagnets

    Also make sure everything is working. * Place the compass about a metre away from the coils. * Turn the power supply on and increase the voltage until the ammeter reads 0.1 Amps.

  2. Strength of an Electromagnet.

    The load might be a motor, a light bulb, a radio or whatever. 3. A small magnetic field is generated in the wire. It is this small magnetic field that is the basis of an electromagnet. The part about the magnetic field might be a surprise to you, yet this definitely happens in all wires carrying electricity.
