1. What is the relationship between magnetic field and distance in a simple conductor?
- The strength increases as we move away from it
- Distance has no effect on a conductor’s magnetic field
- There is an inverse square relationship between them
- The strength decreases as distance increases from it
Show Answer
Answer: Option D. The strength decreases as distance increases from it
