Question
Metal bars A and B have the same length L. Bar B has double the width of A. The bars are parallel to, but far apart from, each other in a uniform Magnetic field.
The current is the same in both. Compare the Hall voltage of bars B and A.
Width = w
Width = 2 w
B
Current i
Current i
Select one:
O Not given
O V Hall A = 4 V Hall B
O V Hall B = 2 V Hall A
%3D
Difficult to say because details of magnetic field is not given
O V Hall A = 2 V Hall B
O V Hall B = 1.41 V Hall A
O V Hall A = 1.41 V Hall B
O V Hall B= 4 V Hall A
