Q22.Two magnetic dipoles X and Y are placed at a separation d , with their axes perpendicular to each other. The dipole moment of Y is twice that of X . A particle of charge q is passing through their mid-point P , at angle θ = 45o with the horizontal line, as shown in figure. What would be the magnitude of force on the particle at that instant? ( d is much larger than the dimension of the dipole) μ0 M × q𝑣 (1) 0 (2) √2 4π d 3 2 μ0 M μ0 2M (3) × q𝑣 (4) × q𝑣 4π d 3 4π d 3 2 2
What This Question Tests
This multi-concept question involves finding the magnetic field at a point due to two perpendicular magnetic dipoles and then calculating the Lorentz force on a charged particle moving through that combined field.
