The temperature at which ferromagnetic alpha iron transforms to paramagnetic alpha iron is

The temperature at which ferromagnetic alpha iron transforms to paramagnetic alpha iron is Correct Answer 770°C

Below 773°C (1,423°F), alpha iron becomes ferromagnetic (i.e., capable of being permanently magnetized), indicating a change in electronic structure but no change in crystal structure.
