What happens to the magnetic field strength inside a solenoid if the current through it is doubled? (2021)
It remains the same
It doubles
It quadruples
It halves
The magnetic field strength inside a solenoid is directly proportional to the current flowing through it. Therefore, if the current is doubled, the magnetic field strength also doubles.

Q: What happens to the magnetic field strength inside a solenoid if the current through it is doubled? (2021)
Solution: The magnetic field strength inside a solenoid is directly proportional to the current flowing through it. Therefore, if the current is doubled, the magnetic field strength also doubles.
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 strength of the magnetic field inside the solenoid depends on the amount of electric current flowing through the wire.
Step 3: Remember the relationship: the magnetic field strength is directly proportional to the current. This means if you change the current, the magnetic field changes in the same way.
Step 4: If the current is doubled, it means you are increasing the amount of electricity flowing through the solenoid.
Step 5: Since the magnetic field strength is directly proportional to the current, doubling the current will also double the magnetic field strength.
