Question

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

Answer 1

Answer:

Magnetic field produced by electric current is decreased as the distance of the current is increased from the wire can be shown with the help of a magnetic compass.

Explanation:

When a magnetic compass is placed close to the current carrying conductor, it shows more deflection.

When the magnetic compass is taken away from the electric current carrying conductor it results in decrease in the deflection shown by the compass. The magnetic deflection further reduces as the compass is taken farther away from the current .

Answer 2

The use of a magnetic compass is the best way to show that the magnetic field produced by a given electric current in the wire decreases as the distance from the wire increases.

• If the current applied to the field develops/shows magnetic property then the field is said to be a magnetic field that forms the basis of electromagnetism.
• A magnetic compass shows deflection when placed very close to the electric field.
• As we move the compass away from the field, the deflection decreases.
• This proves that the magnetic field developed by the electric current decreases as the distance from the field increases.
