What is the relationship between magnetic field strength and distance from a long straight conductor? (2023)
Step 1: Understand that a long straight conductor is a wire that carries electric current.
Step 2: Know that when electric current flows through the wire, it creates a magnetic field around it.
Step 3: Recognize that the strength of this magnetic field is strongest right next to the wire.
Step 4: Learn that as you move further away from the wire, the strength of the magnetic field gets weaker.
Step 5: Remember that this decrease in strength follows an inverse relationship, meaning that if you double the distance from the wire, the magnetic field strength becomes weaker.
