CAIE IGCSE Physics 4.5.4.1 An Experiment to Show That a Force Questions question 1
Fig. 9.1 shows a horizontal wire PQ placed in the gap between the N pole and the S pole of a magnet.
Fig. 9.1
There is a current in the wire in the direction P to Q .
A force acts on the current-carrying wire in the magnetic field.
State the effect of reversing the direction of the current in wire PQ .
