Question

What is the magnetic flux crossing unit area of xy plane generated by magnetic induction b=10(i +2j +.4k)? All quantities are in si units?

Answer 1

Answer:

Explanation:

Magnetic flux = BAcos@

Only the z axis of magnetic field will cause flux

MF = 10(4)(1) = 40 Tm2

Answer 2

Concept Introduction: Magnetic Flux is the magnetic field passing through an area

Given:

We have been Given: The Vector Magnetic Flux density is

$b = 10(i + 2j + 4k)$

To Find:

We have to Find: The Magnetic Flux.

Solution:

According to the problem, Magnetic Flux is,

$m = ba \cos( \alpha )$

Now, Magnetic Flux will only pass through the Z Axis, So,

$m = 10 \times 4 \times 1 = 40 \: t {m}^{2}$

Hence, The Magnetic Flux will be,

$40 \: t {m}^{2}$

Final Answer: The Magnetic Flux will be,

$40 \: t {m}^{2}$
