Metals are highly conductive both electrically and thermally because of its highly ordered crystalline structure of metallic particles. Brick is poor conductor and will be less hot than metal.
Conduction is the mechanism of heat transfer in solids. Solids are composed of closely packed particles arranged in a chain with strong intermolecular forces.
Metals are highly conductive. They have free electrons which are delocalized in the crystal lattice. They can be easily transited through and make the material conductive.
Bricks is poor conductor of heat and odes not conduct electrically, it easily melts at high temperatures and easily cools as well. Therefore, at the surface of sun, the highly conductive metal will be more hotter.

Answer:
0.324 T
Explanation:
Parameters given:
Number of turns, N = 1850
Resistance, R = 30Ω
Area of each turn, A =
Charge in the circuit, q =
The induced EMF in the coil is given as:
EMF is also given in terms of current, I, and resistance, R, as:
V = IR =
=>
Charge, q, is the product of current and time. Hence:
It = q
=>
Hence, magnetic field, B, will be:
The magnitude of magnetic field, |B| will be |-0.324| = 0.324 T
