Option 4 : All statements are correct. 

When a DC current passes through a long straight conductor a magnetizing force, and a static magnetic field, is developed around it. If the wire is then wound into a coil, the magnetic field is greatly intensified producing a static magnetic field around itself forming the shape of a bar magnet giving a distinct North and South pole.

Then by either moving the wire or changing the magnetic field we can induce a voltage and current within the coil and this process is known as Electromagnetic Induction and is the basic principle of operation of transformers, motors and generators.

The trend so far is that the weightage of transport, healthcare and housing has gone up many fold in the new series in the monthly expenditure of an industrial worker, especially consumption of petrol and diesel with the addition of cars to it, while there is decline in overall food basket which is being diversified.?

All actions to address climate change ultimately involve costs. Funding is vital in order for countries like India to design and implement adaptation and mitigation plans and projects. The problem is more severe for developing countries like India, which would be one of the hardest hit by climate change, given its need to finance development. Most countries do indeed treat climate change as real threat and are striving to address it in a more comprehensive and integrated manner with the limited resources at their disposal. With reference to the above passage, the following assumptions have been made: 1. Climate change is not a challenge for developed countries. 2. Climate change is a complex policy issue and also a development issue for many countries. 3. Ways and means of finance must be found to enable developing countries to enhance their adaptive capacity.
