Hi

Could someone help me answer this question..

Describe a first-hand ivestigation to demonstrate the effect o a generated electric current when th strength of the magnet is varied.

(Taken from HSC 2003 Q22)

Thank you.

Essentially, this experiment involves using different-strengthed bar magnets to induce an electric current in a solenoid, from the same height, which is connected to a voltmeter.

HSC Online might help.

Althouugh, the actual question is a 5-marker and you haven't quoted the question in full, so more would be required in an exam.

Pwnage101 haas just made one of the mistakes they were looking for. You can't measure current with a voltmeter, so if you used a voltmeter, you automatically didn't gain full marks.

Exact explanations on how the independent variable was changed, controls etc also were required

My bad - galvanometer. Thanks for the correction.
