MOSFET size design

The load in the inverter circuit shown is a coil of an electromagnet
that requires a current of 0.5 A when turned on. The effective
load resistance varies between 8 and 10​
, depending on
temperature and other variables. A 10 V power supply is
available. The transistor parameters are k'n = 80 and Vtn = 1Volts

Design the size of the MOSFET to meet the requirements.

Any tips on how to start, or useful websites I can surf...thkx a lot!:)
