GEOLOGY

Detailed explanation-1: -The magnetic field inside a solenoid is the sum of magnetic fields due to all loops. So, on increasing the number of loops, the number of electrons causing current increases. Thus magnetic field strength increases. The distance from the current-carrying conductor and the magnetic field are inversely proportional.

Detailed explanation-2: -In a solenoid there are a lot of loops and they are concentrated in the middle, as more loops are added the field lines get larger, therefore making the electromagnet stronger.

Detailed explanation-3: -Strength of Magnetic Field in a Solenoid That’s because each turn of the wire in the coil has its own magnetic field. 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.

Detailed explanation-4: -When the number of turns increases, the magnetic field strength increases. Q. The magnetic field strength of a coil is greater when the number of turns in the coil is higher.

Detailed explanation-5: -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.
