1.	How does the magnetic field set up in a solenoid changes when: (a) number of turns are increased? (b) diameter of the solenoid is increased? (c) strength of the current is increased? (d) a soft iron core is placed in it?
Answer» (a) When number of turns are increased magnetic field will be stronger. (b) When diameter of the solenoid is increased but diameter should be less than the length of solenoid, so that parallel lines should add up to give a stronger field. (c) When strength of current is increased stronger will be the magnetic field produced. (d) When soft iron core is placed in the solenoid very strong magnetic field is produces.

Answer»

(a) When number of turns are increased magnetic field will be stronger.

(b) When diameter of the solenoid is increased but diameter should be less than the length of solenoid, so that parallel lines should add up to give a stronger field.

(d) When soft iron core is placed in the solenoid very strong magnetic field is produces.
