Write a function max$\_$magnitude that accepts a single list full of numbers. It should return the magnitude of the number with the largest magnitude $($the number that is furthest away from zero, converted to its absolute value$).$

max$\_$magnitude$([300,20,-900])$ #$900$

max$\_$magnitude$([10,11,12])$ #$12$

max$\_$magnitude$([-5,-1,-89])$ #$89$ Print.

Hint: use max and abs$!$
