Question

How can you show that the magnetic field produced by a given electric current in the wire decreases as the distance from the increases?

Answer 1

Here's you're Answer Mate

**A magnetic needle shows deflection when it is placed near a current-carrying electric wire.


**As the magnetic needle is taken away from the wire, its deflection decreases and finally the needle align itself along North−South direction. **

**This indicates that the magnetic field produced by a given electric current in the wire decreases as the distance from the increases.

Answer 2

Your answer !!

_______________________________________

If we slowly take away a magnetic compass from a current carrying conductor

Then the deflection of compass decreases .

This shows that magnetic field produced by electric current in the wire decrease as the distance increases .
