प्रश्न
What is the shape of a current-carrying conductor whose magnetic field pattern resembles that of a bar magnet?
Advertisements
उत्तर
The magnetic field produced by a current-carrying solenoid is similar to the magnetic field produced by a bar magnet. Therefore, the shape of the given current-carrying conductor is solenoid.

The graph (fig A) illustrates the correlation between the number of protons (x-axis) and the number of neutrons (y-axis) for elements A, B, C, D, and E in the periodic table. These elements are denoted by the letters rather than their conventional symbols. When the element C, depicted in the graph, undergoes radioactive decay, it releases radioactive rays. When these rays are directed into the plane of the paper in the presence of a magnetic field, as indicated in the fig B, they experience deflection, causing them to move upwards.
