Magnetic Effect...

Household appliances are usually not connected in series because:

The resulting magnetic field at the point O due to the current carrying wire shown in the figure:

A length of wire carries a steady current. It is bent first to form a circular plane coil of one turn. The same length is now bent more sharply to give a double loop of smaller radius. The magnetic field at the centre caused by the same current is

A charge particle is moving in the direction of a magnetic field.The magnetic force acting on the particle:

A DC current flows through a vertical wire in the downward direction. For an observer looking at the wire, the direction of magnetic field at a point between him and the wire is:
