Q: What happens to the magnetic field inside a long solenoid when the current through it is increased?
Solution: The magnetic field inside a long solenoid is directly proportional to the current flowing through it. Increasing the current increases the magnetic field strength.
Steps: 6
Step 1: Understand what a solenoid is. A solenoid is a long coil of wire that creates a magnetic field when electricity flows through it.
Step 2: Know that the magnetic field is the area around the solenoid where magnetic forces can be felt.
Step 3: Recognize that the strength of the magnetic field inside the solenoid depends on the amount of electric current flowing through the wire.
Step 4: Learn that 'directly proportional' means that if one thing increases, the other thing also increases.
Step 5: When the current through the solenoid is increased, the magnetic field strength inside the solenoid also increases.
Step 6: Conclude that more current means a stronger magnetic field inside the solenoid.
