How is the strength of magnetic field affected when current increases?

Open in App Solution

The strength of magnetic field is always proportional to the magnitude of current flowing. Hence, when the current increases, the magnetic field also increases.

I might first point out that however deep you go into the laws of physics, you always end up with “well, that’s just how it is”. I can peel a few of layers off.

Layer 1

Running a current through even a straight wire generates a magnetic field around the wire. This is called Ampère's circuital law - Wikipedia

and dates from 1861. It is, as they say, an observational fact.

Layer 2

This was bundled up with 3 other laws about electrical and magnetic fields to form Maxwell's equations - Wikipedia

. This doesn’t help answer your question directly, because Ampere’s Law is effectively just one of the laws.

A2A: I don't think any theory yet explains how. They only accommodate the observation that it does. You are likely to receive the answer “by induction" or “because the Maxwell-Ampere equation says it must”.

It is an interesting question, as is “Why are Maxwell's equations almost symmetrical?”

I'm personally working on the assumption that the right postulate will eventually clarify these mysteries. I believe I have an answer, but my model is not sufficiently developed for disclosure.

Most likely is due to a larger number of electrons are part of the current. Thus a larger number of atoms participating in generating the magnetic field.

From Wikipedia

“More precisely, the term magnetic moment normally refers to a system's magnetic dipole moment, which produces the first term in the multipole expansion of a general magnetic field. The dipole component of an object's magnetic field is symmetric about the direction of its magnetic dipole moment, and decreases as the inverse cube of the distance from the object.”

The more electrons flowing then the stronger the field.

How do moving charges, such as electric current, produce a magnetic field?

There is no such thing as a magnetic field.

What appears to be a magnetic field is really just changing electric fields. If you analyze the situation using Special Relativity, you can see that it has exactly the effects we see experimentally.

Maxwell, a brilliant man, working with the knowledge we had then and experimental observations, came up with four equations that exactly describe electric and magnetic fields. But no one had discovered relativity, just yet.

we all know that a current-carrying conductor generates a magnetic field around itself, and we can experience that magnetic field by moving another charge around it, as we know a current-carrying conductor exerts a force on the moving charge and it is calculated by the equation F= qv x b. We all know this by Lenz law but what does relativity has to do
