Student Manual

In this experiment we will use the Superconducting Quantum Interference Device (SQUID) that helps us develop an idea of superconductivity. With SQUID we can observe various interesting quantum mechanical effects such as flux quantization, quantum interference and quantum mechanical tunneling at the macroscopic level. We will also use the SQUID as a magnetometer capable of sensing extremely small magnetic fields.
