Two magnets of magnetic moments M1 and M...

Two magnets of magnetic moments `M_1 and M_2` are joined at their centres to form a cross (perpendicular to each other). The combination is suspended in a uniform magnetic field directed vertically upwards. It stands in equilibrium when either of them. makes an angle of `45^(@)` with the vertical field. What is the ratio of their magnetic moments?

Text Solution

Verified by Experts

`M_1 : M_2 = 1:1`
