Answer for Question a). The following conditions are required: 1.The magnitude of current flowing through the circuit should be large. 2. The number of turns in the solenoid must be increased. The greater the number of turns,the stronger will be the magnetic field. 3. A metal such as a soft iron core must be kept in between the coil. This is done to increase the magnetic strength of the solenoid. The Diagram for solenoid is found within the Ncert Class 10 science textbook. Answer for question b). The maximum is at A and C since the magnetic field is denser near the poles. The minimum will be at B since the magnetic field is uniform. The density of magnetic field is same for all points inside the magnet. Answer for question c). By applying Fleming's Left Hand Rule, The direction of magnetic field is perpendicular to the paper in the outward direction i.e. protruding outward towards us from the paper.
