Which of the following relations is correct for permeability ? (A) Н B (B) u = B H (C) H=B.H (D) u = (B + H)​

Answers 2

Answer:

Correct option is C)

The magnetic field by current is calculated by Ampere's circuital law or Bot-Savant law are characterized by magnetic field [B] in Tesla. But when magnetic field is passed through magnetic material they them selves contribute internal magnetic field. So, usually magnetic field strength denoted by H, can be define by the relationship.

H=

μ

m

B

=

μ

o

B

I

Further it can be written as.

B=μ

o

(I+H)

OPTION : C.

Answer:

The relation which is correct for permeability is [tex]\mu=\frac{B}{H}[/tex].

Explanation:

Magnetic permeability also referred to as permeability in electromagnetism is a property of magnetic material which supports the formation of a magnetic field. In other words, it can also be said to be its magnetization capability.

In general, it is the ratio of magnetic intensity and magnetizing field. i.e.

[tex]\mu=\frac{B}{H}[/tex]         (1)

μ=Permeability

B=Magnetic intensity

H=Magnetising field

Hence, the correct relation is [tex]\mu=\frac{B}{H}[/tex]

Which all optional subjects we can choose with PCM in class 11th ? Which optional subject would be best for me if I want to pursue computer science engineering for higher studies ?​

Answer:

With PCM usually there are 2 options -

1) Physical Education (P.E)

2) Computer Science (C.S)

If you don't want much load beside PCM, you can choose P.E and then also you can take C.S in college but as you want to pursue C.S only for higher studies it is better to take C.S in 11th and 12th also because then your base in C.S would be strong
