Two identical short bar magnets each of magnetic moment 12.5 Am2 are placed at a separation of 10 cm. between their centres, such that their axes are perpendicular to each other. Find the magnetic field at a point midway between the two magnets.
Here, M1 = M2 = 12.5 Am²
O1O2 = 10 cm figure.
P is midway between O1 and O2
∴ d – O1P = O2P = 5 cm = 5 × 10–2 m
As P lies an axial line of N1S1,
