What happens to the magnetic field strength inside a solenoid if the number of turns is increased? (2023)
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: Know that the magnetic field strength inside a solenoid depends on two main factors: the amount of electric current flowing through the wire and the number of turns of the wire.
Step 3: Recognize that 'turns' refer to how many times the wire is coiled around the solenoid. More turns mean more loops of wire.
Step 4: Learn that the magnetic field strength is directly proportional to the number of turns per unit length. This means that if you increase the number of turns, the magnetic field strength increases.
Step 5: Conclude that if you increase the number of turns in a solenoid while keeping the current constant, the magnetic field strength inside the solenoid will become stronger.
