SUMMARY
The magnetic flux through a 5 cm² area loop in a magnetic field defined by B=<40i-18k>T is calculated using the formula Flux=B.A. The resulting flux is 90 * 10^-4 Wb, which can be negative due to the direction of the magnetic field relative to the area vector of the loop. The negative sign indicates the direction of the flux, not the magnitude, which is always considered a positive quantity.
