← ScienceWhich effect commonly arises when placing a magnetic field near a superconducting quantum interference device (SQUID)?
A)Flux quantization in the SQUID loop✓
B)Increased thermal noise in the circuit
C)Suppression of the Josephson effect
D)Mechanical stress due to magnetostriction
💡 Explanation
When placing a magnetic field near a SQUID, flux quantization occurs due to the Meissner effect and the formation of Cooper pairs, leading to integer multiples of the flux quantum penetrating the loop. Therefore, flux quantization results, rather than increased noise, Josephson suppression, or mechanical stress, which require different mechanisms or conditions.
