Which of the following statements is true about the magnetic field due to a long straight conductor? (2020)

Which of the following statements is true about the magnetic field due to a long straight conductor? (2020)

Step 1: Understand what a long straight conductor is. It is a wire that is very long and straight, like a power line.
Step 2: Learn about magnetic fields. A magnetic field is an area around a magnet or a current-carrying wire where magnetic forces can be felt.
Step 3: Know that when electricity flows through the wire, it creates a magnetic field around it.
Step 4: Realize that the strength of this magnetic field is strongest right next to the wire.
Step 5: Understand that as you move further away from the wire, the strength of the magnetic field gets weaker.
Step 6: Conclude that the statement 'the magnetic field due to a long straight conductor decreases with increasing distance from the conductor' is true.
