What happens to the magnetic field strength inside a solenoid if the current is increased? (2021)
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 through the wire.
Step 3: Learn about magnetic field strength. The magnetic field strength is how strong the magnetic field is inside the solenoid.
Step 4: Recognize the relationship between current and magnetic field strength. When the current increases, it means more electric charge is flowing through the wire.
Step 5: Conclude that if more current flows, the magnetic field strength inside the solenoid becomes stronger.
Step 6: Remember that this relationship is direct, meaning if you double the current, the magnetic field strength also doubles.
