Detailed explanation-1: -The strength of the magnetic field produced by the solenoid can be increased: By placing soft iron inside the solenoid. By increasing the number of turns of the coil. By increasing the current flowing through the solenoid.

Detailed explanation-2: -The strength of the magnetic field around a solenoid can be increased by: increasing the number of turns on the coil. increasing the current. placing an iron core inside the solenoid.

Detailed explanation-3: -Answer and Explanation: The magnetic field is strongest inside the coil of a solenoid. Inside the coil of a solenoid the magnetic field lines are uniform and tightly packed together which creates a stronger magnetic field here than anywhere outside of the solenoid.

Detailed explanation-4: -The magnetic field of solenoid is directly proportional to the current passing and the number of turns and has a proportionality constant which depends on material of conductor, instead of area magnetic field depends upon the length of solenoid.

Detailed explanation-5: -Strength of Magnetic Field in a Solenoid Adding more turns to the coil of the wire increases the strength of the field. Increasing the amount of current flowing through the coil also increases the strength of the magnetic field.
