Q: What is the effect of increasing the current in a solenoid on its magnetic field strength? (2021)
Solution: Increasing the current in a solenoid increases its magnetic field strength, as the magnetic field is directly proportional to the current.
Steps: 5
Step 1: Understand what a solenoid is. A solenoid is a coil of wire that creates a magnetic field when electricity flows through it.
Step 2: Know what current means. Current is the flow of electric charge, measured in amperes (A).
Step 3: Recognize the relationship between current and magnetic field. The magnetic field strength in a solenoid is directly related to the amount of current flowing through it.
Step 4: Realize that increasing the current means more electric charge is flowing through the solenoid.
Step 5: Conclude that as you increase the current, the magnetic field strength also increases.
