Calculate the magnetic flux through your head when the B⃗ field of a 1.4-T MRI machine passes through your head. Assume the cross-sectional area of the head is 200 cm2. Express your answer in tesla meters squared.

The magnetic flux is 0.028 T. m²

Explanation:

Given;

magnetic field strength, B = 1.4-T

cross sectional area, A = 200 cm²

Area in m² = 200 cm² x (1m/100cm) ²

= 200 cm² x 1m²/10000cm²

= 200 m² / 10000

= 0.02 m²

To determine the magnetic flux through your head when the magnetic field is 1.4-T, we apply magnetic flux equation below;

Φ = BA

Where;

Φ is the magnetic flux

B is the magnetic field

A is area

Φ = BA

Φ = 1.4 x 0.02 = 0.028 T. m²

Therefore, the magnetic flux through your head is 0.028 T. m².
