Answer:
B
Explanation:
Because according to the bolye law . Pressure is inversely propotional to volume . So higher the pressure lower the volume. P1×V1=P2×V2
Therefore, the magnitude of magnetic field at a distance 1.10cm from the origin is 27.3mT
<u>Explanation:</u>
Given;
Number of turns, N = 1000
Inner radius, r₁ = 1cm
Outer radius, r₂ = 2cm
Current, I = 1.5A
Magnetic field strength, B = ?
The magnetic field inside a tightly wound toroid is given by B = μ₀ NI / 2πr
where,
a < r < b and a and b are the inner and outer radii of the toroid.
The magnetic field of toroid is

Substituting the values in the formula:


Therefore, the magnitude of magnetic field at a distance 1.10cm from the origin is 27.3mT
