Questions & Step-by-Step Solutions
In a solenoid, what is the effect of increasing the number of turns per unit length on the magnetic field strength?
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 what 'turns per unit length' means. This refers to how many loops of wire are in a certain length of the solenoid.
Step 3: Realize that the magnetic field strength is related to the number of turns. More turns mean more loops of wire for the current to flow through.
Step 4: Remember that when you increase the number of turns per unit length, you are effectively increasing the amount of wire in a given space.
Step 5: Conclude that with more turns, the magnetic field strength becomes stronger because the magnetic effects of each loop add up.
