Vedclass · Answer

(D) The magnetic field produced by a current-carrying solenoid depends on the following factors: $1$. The magnitude of the current flowing through the solenoid: The magnetic field strength is directly proportional to the current. $2$. The number of turns in the solenoid: The magnetic field strength is directly proportional to the number of turns per unit length. $3$. The nature of the core material: If a soft iron rod is placed inside the solenoid,it acts as an electromagnet,significantly increasing the magnetic field strength compared to an air core.
