What happens to the magnetic field inside a solenoid when the current is increased? (2020)
It decreases
It remains constant
It increases
It becomes zero
The magnetic field inside a solenoid is directly proportional to the current. Therefore, if the current is increased, the magnetic field also increases.

Q: What happens to the magnetic field inside a solenoid when the current is increased? (2020)
Solution: The magnetic field inside a solenoid is directly proportional to the current. Therefore, if the current is increased, the magnetic field also increases.
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 that the magnetic field is the area around the solenoid where magnetic forces can be felt.
Step 3: Learn that the strength of the magnetic field inside the solenoid depends on the amount of electric current flowing through the wire.
Step 4: Remember that 'directly proportional' means that if one thing increases, the other thing also increases.
Step 5: Conclude that if you increase the current flowing through the solenoid, the magnetic field inside it will also increase.
