How do I calculate norm with a for loop?

So I have a set of data in a matrix represented as x y coordinates and another set of data as well with the same column dimensions but different row dimensions. How can I create a for loop to take the norm of each data point from each matrix to get the distance between every single coordinate point? In other words say I have matrix A= [1 2; 3 4; 5 6] and B = [9 8; 7 6; 5 4; 3 2; 1 0] where I want to take the norm of 1,2 and 9,8, 1,2 and 7,6 1,2 and 5,4 and so on.
