प्रश्न
A copper conductor is placed over two stretched copper wires whose ends ate connected to a D.C. supply as shown in the diagram.
- What should be the magnetic poles at the points A and B lying on either side of the conductor to experience the force in the upward direction?
- Name the law used to find these polarities.

उत्तर
- A - North pole
B - South pole - The Fleming's left hand rule is the law that was applied to ascertain the polarities.
