Hi guys,
We have to finish this prac report for homework and was just wondering is someone could check my answers to see if I'm on the right track.
Ok so our experiment was observing Faraday's law (we moved a magnet in and out of a coil and measured change in flux and current through a datalogger).
These were my answers:
Aim: To observe Faraday’s experiment, known as induction. It demonstrates that relative movement between the magnet and the coil generates an induced current, due to a change in flux.
Hypothesis: I believe that as the number of turns decreases, the induced current decreases. This can be seen through the formula
Apparatus: datalogger, voltage probe, plastic former, 3m copper wire, magnet, retort stand, boss head, clamp
Method:
Set up the apparatus as shown
Wind 16 turns CLOCKWISE onto the plastic former
Insert the magnet, measuring the magnitude and direction of the induced EMF
Wind a further 8 turns ANTICLOCKWISE, measure again
Wind another 8 turns ANTICLOCKWISE, measure again
Independent: The number of turns on the plastic former.
Dependent: The induced current formed by relative movement between the magnet and the coil.
Control Variables: The speed of the movement of the magnet in the coil.
