What type of matter do alloys fall under?

Alloy, metallic substance composed of two or more elements, as either a compound or a solution. The components of alloys are ordinarily themselves metals, though carbon, a nonmetal, is an essential constituent of steel. Alloys are usually produced by melting the mixture of ingredients.

Magnetic field, B = 0.88 T

Explanation:

It is given that,

The dimension of rectangular surface is 2.80 cm by 3.15 cm. The area of rectangular surface is,

Angle between the uniform magnetic field and the horizontal,

Magnetic flux,

Let B is the magnitude of magnetic field in which the rectangular surface is placed. It is given by :

is the angle between magnetic field and the area

Here,

B = 0.88 T

So, the magnitude of magnetic field is 0.88 T. Hence, this is the required solution.
