Question: What is the effect of increasing the current in a solenoid on the magnetic field inside it?

Options:

  1. Increases
  2. Decreases
  3. Remains the same
  4. Becomes zero

Correct Answer: Increases

Solution:

The magnetic field inside a solenoid is directly proportional to the current flowing through it. Therefore, increasing the current increases the magnetic field strength.

Questions & Step-by-Step Solutions

What is the effect of increasing the current in a solenoid on the magnetic field inside it?
  • 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: Realize 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 become stronger.
