Question: What happens to the magnetic field strength inside a solenoid if the current through it is doubled? (2021)

Options:

  1. It remains the same
  2. It doubles
  3. It quadruples
  4. It halves

Correct Answer: It doubles

Exam Year: 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.

Questions & Step-by-Step Solutions

What happens to the magnetic field strength inside a solenoid if the current through it is doubled? (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 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.
