Disclosed is an inductor (200, 1000, 1300) comprising an inductor coil (202) and terminals (204a, 204b; 1310a, 1310b). The inductor (200, 1000, 1300) is substantially symmetric about a symmetry axis. The inductor coil (202) has a first loop (206a; 1004; 1002) and a second loop (206b; 1006; 1008) arranged such that current in the first loop (206a; 1004; 1002) travels in a direction that is opposite to current in the second loop (206b; 1006; 1008) such that electromagnetic field components emanating at a certain distance from the first loop (206a; 1004; 1002) and the second loop (206b; 1006; 1008) also have opposite directions and tend to counteract each other. |
