It is very common application to drive a relay with a MOSFET. From household applications to automotive are using this circuit. There are some aspects to consider like the stress on the MOSFET, the level of driving voltage to guarantee MOSFET saturation, the level of the actual voltage applied to the relay coil if enough to meet the requirement and
MOSFET is not well discussed in the undergrads; much more how to designing MOSFET switch. MOSFET stands for metal oxide semiconductor field effect transistor. Actually it is easier than BJT if we are talking a switch circuit. Nowadays MOSFET is very popular in circuit designs. Such in automotive, power supply and general electronics as a low side and high side
