Answer:
The magnetic field due to a solenoid is given as : where, is the permeability of the medium. n is the number of turns or loops in the coil. I is the current flowing in the solenoid.
The magnetic field due to a solenoid can be increased by increasing the number of turns, current and placing an iron core inside the solenoid.
So, the correct option are:
(1) using more wire loops
(2) using a larger current
Hence, the correct options are (a) and (c).

Answer and Explanation:
Both clouds and fog are closely related to precipitation.
This can be explained first by the formation of clouds and fog, which begin when the air contains water vapor. This <u>water vapor is produced when there is an accumulation of moisture in the enviroment which leads to the formation of clouds. A similar process occurs with the formation of fog, which comes from saturation, that occurs after the evaporation and condensation processes that take place after precipitation (water cycle). </u>
Moreover, some types of clouds (cumulonimbus) are associated with precipitation as they could be accompanied by climatic phenomenon such as rain and snow.
