Chapter 23, Problem 1CQ

Explain the difference between a magnetic field and a magnetic flux.

To determine

The difference between magnetic flux and magnetic field.

Answer to Problem 1CQ

The magnetic field is the strength of the field and the flux is the amount of field that passes through unit area.

Explanation of Solution

The magnetic flux is defined as the number of magnetic lines of force that passes through the any surface area in magnetic field. It is denoted by phi $\left(\varphi \right)$ and its S.I unit is Weber. The magnetic field is the strength of the field.

The magnetic field is defined as the magnetic flux that passes through the unit surface area of body. It is denoted by $B$ and its S.I unit is Tesla or $\left(\text{Wb}/{\text{m}}^2\right)$. The flux is the amount of field that passes through unit area.

Conclusion:

Therefore, the magnetic field is the strength of the field and the flux is the amount of field that passes through unit area.
