Try this:
figure
hp{1} = polarplot([45 160; 0 0]*pi/180, [1 1; 0 0], '--k', 'DisplayName','Induction');
hold on
hp{2} = polarplot([160; 0]*pi/180, [1; 0], '-k', 'DisplayName','Field');
polarplot([40 50; 45 45]*pi/180, [0.8 0.8; 1 1], '-k')
polarplot([155 165; 160 160]*pi/180, [0.8 0.8; 1 1], '-k')
hold off
lgd = legend([hp{1}(1), hp{2}(1)], 'Induction','Field', 'Location','southoutside');
title(lgd, '\itB\rm at 45°')
producing:

There are too many spaces in the handle vector of the legend call. Cell arrays are comma-separated lists, and if spaces appear between the subscript references, this confuses MATLAB.
Note that the extra spaces in the title call will likely also throw an error. This will cause problems for the text interpreter, since spaces in a character vector are significant, and it will not interpret the TeX calls ‘\it’ and ‘\rm’ correctly.
Please just use my code as I wrote it!
