Question

Two short magnets of equal dipole moments M are fastened perpendicularly at their centre (figure 36-Q1). The magnitude of the magnetic field at a distance d from the centre on the bisector of the right angle is
(a) μ04πMd3
(b) μ04π√2 Md3
(c) μ04π2√2Md3
(d) μ04π2Md3
Figure

Answer 1

Correct option will be option c .

Two short magnets of equivalent dipole minutes M are affixed oppositely at their focuses. The extent of the attractive field at a separation d from the inside on the bisector of the right angle will be (c) μ0 / 4π 2√2 M / d^ 3

Answer 2

Answer: C

Explanation:

Calculate B along axis for both magnets and then find their resultant
