Q: What is the effect of increasing the distance from a long straight current-carrying wire on the magnetic field strength?
Solution:
According to the Biot-Savart Law, the magnetic field strength decreases with increasing distance from the wire.
Steps: 4
Show Steps
Step 1: Understand that a long straight wire carrying an electric current creates a magnetic field around it.
Step 2: Recognize that the strength of this magnetic field is strongest close to the wire.
Step 3: Learn that as you move further away from the wire, the magnetic field strength gets weaker.
Step 4: Remember that this relationship is described by the Biot-Savart Law, which states that the magnetic field strength decreases with distance.
