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

Options:

  1. Increases the magnetic field
  2. Decreases the magnetic field
  3. No effect on the magnetic field
  4. Reverses the direction of the magnetic field

Correct Answer: Increases the magnetic field

Solution: 

Increasing the current in a wire increases the magnetic field around it, as per the Biot-Savart Law.

Questions & Step-by-Step Solutions

What is the effect of increasing the current in a wire on the magnetic field around it?
  • Step 1: Understand that a wire carrying an electric current creates a magnetic field around it.
  • Step 2: Know that the strength of this magnetic field depends on the amount of current flowing through the wire.
  • Step 3: Realize that if you increase the current (more electricity flowing), the magnetic field becomes stronger.
  • Step 4: Remember that this relationship is described by the Biot-Savart Law, which explains how current creates magnetic fields.
