Questions & Step-by-Step Solutions
In a solenoid, what factor does NOT affect the strength of the magnetic field inside it?
Step 1: Understand what a solenoid is. A solenoid is a coil of wire that creates a magnetic field when an electric current passes through it.
Step 2: Identify the factors that affect the strength of the magnetic field inside a solenoid. These include the number of turns of wire per unit length, the amount of electric current flowing through the wire, and the type of material inside the solenoid (permeability).
Step 3: Recognize that the length of the solenoid does not change the strength of the magnetic field. Instead, it is the density of the turns and the current that matter.
Step 4: Conclude that while the length of the solenoid can affect the overall magnetic field in some contexts, it does not directly affect the strength of the magnetic field inside the solenoid itself.
