Five long wires A, B, C, D and E, each carrying current I are A arranged to form edges of a pentagonal prism as shown in Fig. 4.6. Each carries current out of the plane of paper.
This question refers to a figure in the original PDF.
- (a)What will be magnetic induction at a point on the axis O? AxisE R is at a distance R from each wire.
- (b)What will be the field if current in one of the wires (say A) is switched off?
- (c)What if current in one of the wire (say) A is reversed? D C Fig. 4.6
