Consider two identical wire-frame cubes (a) and (b). The magnitude of the magnetic field at the centre of the cube in (a), produced by the currents in its edges as shown in standard physics problems, is B0. If identical currents flow through the configuration shown in (b), the magnitude of the magnetic field at the centre of the cube in (b) will be:
- 1√2B0
- 232B0
- 32B0
- 4√3B0✓
Correct answer
√3B0
