Chapter 21, Problem 2Q

To determine

To Explain: The difference between magnetic flux and magnetic field should be discussed.

Answer to Problem 2Q

Magnetic field is a vector quantity whereas, magnetic flux is a scalar quantity.

Explanation of Solution

Introduction:Magnetism is a force that works on moving electric charge as well as magnetic materials which are near a magnet.

Difference between magnetic flux and magnetic field is given below:

Magnetic flux	Magnetic field
It represents the quantity of magnetic lines of force, which are produced by a magnet.	It is a force field which surrounds either a wire carrying an electric current or a magnet.
The magnetic flux through a surface is the sum of magnetic field lines passing through that surface.	Not dependent on magnetic flux.
It is a scalar quantity.	It is a vector quantity.
It depends on the strength of magnetic field.	It depends only on the magnetic force that it produces.
Formula: $\varphi =BA$	Formula: $F=qvB$
SI Unit: Weber	SI Unit: Tesla

Conclusion: Magnetic flux and magnetic field are not the same.
